====== 0x28 LOGIC_IC_TEST_VECTOR (t48) ======
send 28 vv pp 00 n1 n2 n3 n4 [test vector]
recv 28 00 pp 00 00 00 00 00 [test reply]
Performs a logic test.</br>
vv&0x7F sets VCC voltage.
voltagemap_logic_vcc[4]={ 5, 3.3, 2.5, 1.8 };
If vv&0x80 is true set pulldowns otherwise pullups.</br>
pp is the number of pins which must be an even number from 2 to 40,
corresponding to the number of pins of the chip under test. Setting
a value higher than 40 will lock up the T48.</br>
n1 n2 n3 n4 is a 32 bit sequence number N which is typically incremented for each
test. If N is zero the logic test sets voltages and assigns VCC and GND
according to the test vector, it also resets all ISP pins to input. If N is non-zero the VCC voltage setting is ignored,
VCC and GND are not reassigned, ISP values are unchanged. Pullups or pulldowns are still set according to vv&0x80.</br>
'''[test vector]''' consists of 24 bytes of which only the first pp/2 are significant. Each nyble corresponds to
a pin, lowest nyble first. That is low nyble of the initial byte is pin 1
and the high nyble pin2. The nyble can take values 0 through 8 representing 0, 1, L, H, C, Z, X, G, and V respectively.</br>
'''[test reply]''' contains the logic state of each pin in the same format as the test vector. Each nyble will be 0 or
1.
</br>
A pin can be tested for high impedance (tri-state) by performing the same test twice: once with pullup and the second time
with pulldown. If the pin changes from 1 to 0 it is tri-state otherwise the pin is driving it.</br>
The test vector will silently allow VCC and GND assignments to pins which do not support it.</br>
By keeping the sequence number non-zero VCC voltages can be set to values not normally supported by logic test. ISP settings can also be retained.</br>
The pin numbers in the test vector and response are the pins of the inserted IC: not the pin numbers of the ZIF socket.
====== 0x29 AUTO_FIND (t48) ======
send 29 00 00 00 00 00 00 00
recv 29 00 pp 00 00 00 00 00 [pins]

byte is set to 1 then the pin is active, 0 otherwise.

0x28 LOGIC_IC_TEST_VECTOR (t48)
send 28 vv pp 00 n1 n2 n3 n4 [test vector]
recv 28 00 pp 00 00 00 00 00 [test reply]

Performs a logic test.
vv&0x7F sets VCC voltage. 

voltagemap_logic_vcc[4]={ 5, 3.3, 2.5, 1.8 };

If vv&0x80 is true set pulldowns otherwise pullups.
pp is the number of pins which must be an even number from 2 to 40, corresponding to the number of pins of the chip under test. Setting a value higher than 40 will lock up the T48.
n1 n2 n3 n4 is a 32 bit sequence number N which is typically incremented for each test. If N is zero the logic test sets voltages and assigns VCC and GND according to the test vector, it also resets all ISP pins to input. If N is non-zero the VCC voltage setting is ignored, VCC and GND are not reassigned, ISP values are unchanged. Pullups or pulldowns are still set according to vv&0x80.

[test vector] consists of 24 bytes of which only the first pp/2 are significant. Each nyble corresponds to a pin, lowest nyble first. That is low nyble of the initial byte is pin 1 and the high nyble pin2. The nyble can take values 0 through 8 representing 0, 1, L, H, C, Z, X, G, and V respectively.

[test reply] contains the logic state of each pin in the same format as the test vector. Each nyble will be 0 or 1.

A pin can be tested for high impedance (tri-state) by performing the same test twice: once with pullup and the second time with pulldown. If the pin changes from 1 to 0 it is tri-state otherwise the pin is driving it.

The test vector will silently allow VCC and GND assignments to pins which do not support it.
By keeping the sequence number non-zero VCC voltages can be set to values not normally supported by logic test. ISP settings can also be retained.
The pin numbers in the test vector and response are the pins of the inserted IC: not the pin numbers of the ZIF socket.

0x29 AUTO_FIND (t48)
send 29 00 00 00 00 00 00 00
recv 29 00 pp 00 00 00 00 00 [pins]

Attempt to detect which pins are active in the ZIF socket. This is used by logic tests when the "Auto Find" button is clicked. pp is the number of pins checked and is always 40 (0x28). [pins] is a list of pp pins one pin per byte. If the corresponding byte is set to 1 then the pin is active, 0 otherwise.

0x2d RESET_PIN_DRIVERS (t48)
send 2d 00 00 00 00 00 00 00

send 31 00 00 00 00 00 00 00

Enable pull up for all pins and set all pins to input. Any pins assigned to VPP/VCC/GND are unchanged.

0x32 SET_PULLDOWNS (t48)
send 32 00 00 00 00 00 00 00

Enable pull down for all pins and set all pins to input. Any pins assigned to VPP/VCC/GND are unchanged.

0x33 MEASURE_VOLTAGES (t48)
send 33 00 00 00 00 00 00 00
recv 33 00 00 00  00 00 00 00  pp pp pp pp  uu uu uu uu  vv vv vv vv  ii ii ii ii

Measures voltages.
pp is vpp voltage.vpp = (pp*0xf78/0x1000)/100.0
uu is usb voltage. vusb = (uu*0xccf6/0x27000)/100.0
vv is vcc voltage. vcc = ((vv*0xb32e/0x27000)-0x14)/100.0
ii is vccio voltage. vccio = (ii*0x294/0x1000)/100.0

0x35 READ_PINS (t48)
send 35 00 00 00 00 00 00 00
recv 35 00 00 00 00 00 00 00 aa bb cc dd ee ff gg 00

Reads pins and returns bits for all 56 pins on aa bb cc dd ee ff gg
first pin is lsb of aa. ff and gg correspond to the ISP with J1 being the LSB of ff.
Note: J12, J14 and J16 always read as 0: they are not connected to separate I/O pins.
J12 is internally connected to ZIF pin 21.

0x36 SET_OUT (t48)
send 36 xx 00 00 ii 00 00 00

Sets pin ii to value xx (00 or 01) AND sets the pin to output push-pull 50 MHz.
xx values 0 through 39 (decimal) correspond to pins 1 through 40 of the ZIF.
xx values 40 through 56 (decimal) correspond to J1 through J16 of the ISP.
Attempting to set J12, J14 or J16 has no effect.

0x3E PIN_DETECT
send 3E 00 aa bb 00 00 00 00
recv  3E 00 aa bb 00 00 00 00 b0 b1 b2 b3 b4 b5 b6 00
