Figure 12
shows these four interrupt configuration modes. They are programmable
through the HcHardware Configuration register (see
Section 10.4.1
), which is also
used to disable or enable the signals.
8.6.2
Interrupt output pin (INT)
To program the four configuration modes of the HC’s interrupt output signal (INT), set
InterruptPinTrigger and InterruptOutputPolarity (bits 1 and 2) of the
HcHardwareConfiguration register (20H to read, A0H to write). InterruptPinEnable
(bit 0) is used as the master enable setting for pin INT.
INT has many associated interrupt events as shown as in
Figure 13
.
