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 to read, A0H to 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 Hc PInterrupt register (24H to read, A4H to write)
changes the status of pin INT1 when the corresponding bits of the
Hc PInterruptEnable register (25H to read, A5H to 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 to read, 83H to
write) affect only bit OPR_Reg of the Hc PInterrupt register. They cannot directly
change the status of pin INT1.
