T48 0x24 command byte seems to be Adapter detection/DRM.
Here are the queries to the T48 for some adapters:

0x3E (pin detect)
pin detect response in the form 3E00xxxx000000XXXXXXYYYYYY0000, where XXXXXX seems to be one row of pin state, and YYYYYY the other. x x x x x x x x x x x x x x x x - - - - U FFFF00 FFFF00 x x x x x x x x x x x x x x x x - - - - x x x x x x x x x x x x x x x x x - - - U FFFF80 FFFF00 x x x x x x x x x x x x x x x x - - - - x x x x x x x x x x x x x x x x - - - - U FFFF0C FFFF00 x x x x x x x x x x x x x x x x - - x x x x x x x x x x x x x x x x x x - - x x U FFFF30 FFFF00 x x x x x x x x x x x x x x x x - - - - x x - - - - - - - - - - - - - - - - - - U 000000 00C000 - - - - - - - - - - - - - - - - - - - - - - x x - - - - - - - - - - - - - - - - U 000000 003000 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - U 030000 000000 x x - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - U 060000 000000 - x x - - - - - - - - - - - - - - - - -
(0x34) Was SET_DIR
The old SET_DIR command (0x34) on the T48 responds with 12 bytes:
34 00 18 00 00 00 00 00 00 00 00 00
Anyone any idea what this represents? Assigning some of ISP to GND/VCC/VPP does produce some non-zero values for the last 4 bytes but can't find a pattern. Calling pin reset or even end transaction doesn't reset the values in the reponse.
