ATA6264 [Preliminary]
Because the diagnosis commands are non-latching commands, any new serial interface com-
mands, except watchdog triggering (6A55) and the Kx switching commands (9Cxx), interrupt the
diagnosis.
Note: a, b, and c represent the IASG number in binary format; only 001 = IASG1, 010 = IASG2,
011 = IASG3, 100 = IASG4, and 101 = IASG5 are valid commands
Because the IASG commands are non-latching commands, any new serial interface command,
except watchdog triggering (6A55) and the Kx switching commands (9Cxx), interrupts the IASG
function.
