8.7. /INT Output during Operation of Interrupt Function
8.7.1. Shared /INT output
The /INT interrupt output pin is shared as the output pin for interrupt events from three functions: the periodic
interrupt function, Alarm W function, and Alarm D function.
The /INT pin outputs at low level when any one of these interrupt events occurs.
When an interrupt has occurred (/INT = "L"), the CTFG, WAFG, and DAFG flags are read to determine which type of
interrupt event has occurred (indicated by a "1" value in the corresponding flag).
The /INT setting must be cleared via bit manipulation when another interrupt occurs or when the same interrupt
occurs again (this sets /INT to high impedance).
8.7.2. WAFG, DAFG, and /INT output
The following illustrates how the WAFG and DAFG bits relate to /INT output with regard to the operation of the
Alarm W function and Alarm D function.
