Description

This component provides basic time, calender and alarm functionality.

File(s):

Asynchronous 8-bit TMRx operation is selected to use an external 32768 Hz crystal. TMRx is configured to generate an interrupt and call a handler function.

Function Documentation

◆ px_async_tmr_init()

void px_async_tmr_init ( void )

Initalises TMRx to use an external 32768 Hz crystal.

TMRx is configured to generate an interrupt once a second, during which the date and time is updated and checked if an alarm has occurred.

◆ px_async_tmr_int_enable()

void px_async_tmr_int_enable ( void )

Enable TMRx interrupt.

Definition at line 99 of file px_async_tmr.c.

◆ px_async_tmr_int_disable()

bool px_async_tmr_int_disable ( void )

Disable TMRx interrupt.
