====== 0x2E SET_VCC_PIN (and voltage) (t48) ======
send 2e 00 00 00 00 00 00 00 aa bb cc dd ee ff gg 00 xx 00 00 00 yy 00 zz 00
Set which pins are VCC in aa bb cc dd ee ff gg according to vcc pin map.
 
xx is 00 or 01 where 01 enables VCC on ISP-connector
 
yy is written straight to DAC hold register R32_DAC_R12BDHR2. Some code writes it to 0x96,
writing 0x01 e.g. breaks reading voltages with cmd 0x33 but with 0x00 it still works.
 
xx is 00 or 01 where 01 enables VCC on ISP-connector.
 
zz is VCC voltage 01 to 3F. 00 means don't set VCC.

====== 0x2F SET_VPP_PIN (and vpp and vccio voltage) (t48) ======
send 2f 00 00 00 00 00 00 00 aa bb cc dd xx 00 00 00
Set which pins are VPP in aa bb cc dd according to vpp pin map.
 
xx is 00 or 01 where 01 enables VPP on ISP-connector.
 
send 2f 01 00 00 00 00 00 00 xx 00 00 00
Sets vpp voltage xx 00 to 3f from 9.31 to 25.16 volts, ca 0.25V per step.
 
send 2f 02 00 00 00 00 00 00 xx 00 00 00
Sets vccio voltage 00 to 04. 0=2.35, 1=2.47, 2=2.93, 3=3.23, 4=3.45

====== 0x30 SET_GND_PIN (t48) ======
send 30 00 00 00 00 00 00 00 aa bb cc dd ee ff gg 00 xx 00 00 00
Set which pins are gnd in aa bb cc dd ee ff gg according to gnd pin map.
 
xx is 00 or 01 where 01 enables EGND on J6/J8/J16 on ISP-connector.

====== 0x31 SET_PULLUPS (t48) ======
send 31 00 00 00 00 00 00 00
Enable pull up for all pins and set all pins to input.

====== 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.

====== 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.

====== 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.

====== 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
