Interrupt output pin (INT)
To program the four conguration modes of the HC’s interrupt output signal (INT), set
bits 1 and 2 of the HcHardwareConguration register (20H - Read, A0H - Write). Bit 0
is used as the master enable setting for pin INT.
INT has many interrupt events. The relationship between pin INT and its interrupt
events is shown as in Figure 13.
