Interrupt Control Functions
When the 82C55A is programmed to operate in
mode 1 or mode 2, control signals are provided that
can be used as interrupt request inputs to the CPU.
The interrupt request signals, generated from port C,
can be inhibited or enabled by setting or resetting
the associated INTE flip-flop, using the bit set/reset
function of port C.
This function allows the Programmer to disallow or
allow a specific I/O device to interrupt the CPU with-
out affecting any other device in the interrupt struc-
ture.
INTE flip-flop definition:
(BIT-SET)DINTE is SETDInterrupt enable
(BIT-RESET)DINTE is RESETDInterrupt disable
Note:
All Mask flip-flops are automatically reset during
mode selection and device Reset.
