Chapter 8 Hardware Configuration
8.2.3 I/O Interrupts
There are 32 I/O interrupts (I0~I31).
I/O interrupts are used by special high-speed modules. Users can set interrupt conditions and interrupt
numbers for a special high-speed module by means of HWCONFIG, and download the program created in
ISPSoft to the special high-speed module. If an interrupt condition is met when the high-speed module runs,
the corresponding interrupt will be executed.
Take AH04HC-5A for instance. The steps of setting AH04HC-5A are as follows.
(1) After users click CH0~3 parameter setting in the Parameter Setting window, they can set
CH1/CH2/CH3/CH4 compariosn function, and CH1/CH2/CH3/CH4 comparison interrupt output
selection.
(2) After the users click CH0~3 comparison value setting, they can type comparison values in the Initial
cells.
