Product data
8.6.2 HC’s interrupt output pin (INT1)
To program the four configuration modes of the HC’s interrupt output signal (INT1),
set bits InterruptPinTrigger and InterruptOutputPolarity of the
HcHardwareConfiguration register (20H - read, A0H - write). Bit InterruptPinEnable is
used as the master enable setting for pin INT1.
INT1 has many associated interrupt events, as shown as in
The interrupt events of the HcµPInterrupt register (24H - read, A4H - write) changes
the status of pin INT1 when the corresponding bits of the HcµPInterruptEnable
register (25H - read, A5H - write) and pin INT1’s global enable bit (InterruptPinEnable
of the HcHardwareConfiguration register) are all set to enable status.
However, events that come from the HcInterruptStatus register (03H - read, 83H -
write) affect only the OPR_Reg bit of the HcµPInterrupt register. They cannot directly
change the status of pin INT1.
