Motorola Interrupt Timing (slave mode)
Note 1:
Timing valid for active-high push-pull signal. Timing for active-low push-pull
signal is the same.
In the case of an open-drain output, reset times (T23, T31) depend on
external devices.
Note 2:
Function of DTACK is described logically as:
DTACK = CS x DACK x INTAi + DS x R/W
INTAi is an internal signal. It is generated if the interrupt acknowledge cycle is
considered valid.
