BA08 Run 2 functions? (they appear to be non-trivial!)
BA0901 Read RAM@0136 (4 bytes)
BA0902 Read RAM@013A (4 bytes)
BA0903 Read RAM@013E (4 bytes)
BA0904 Read RAM@0142 (4 bytes)
BA0905 Read RAM@0146 (4 bytes)
BA0906 Read RAM@014A (2 bytes) and incl. 0001 (RAM@1981&0x07) or 0000 (secure mode?)
BA0A01 \_ Seems to muck around with
BA0A02 / the GPIO pin states - only 2 options though!
BA0B01 \_ Seems to return bit status
BA0B02 / for many of the GPIO pins
BA0CXXXXXX Returns a byte, depending on which bit is set in XXXXXX (mask FFFF80)
BA0D Returns 0 or 1 depending on RAM@0234,0230
BA0E Reads RAM@1A52 1 byte
BA0F01 Reads 2 bytes by calling 2 functions
BA0F02 Reads 2 bytes by calling only the first of those 2 functions
BA1001 Calls a function with 1 \_ Returns 2 bytes
BA1002 Calls a function with 0 / No idea what they're doing though
BA1101 \_ If bits in RAM@1981 are 0 (in secure mode?) else return condition not correct
BA1102 / 1 runs 7 functions, 2 runs only the first.
VDO EOL Holy Trucking Moly
