3.2.1 RTC_HOURS
This macro is used to initialize the hours value in the clock structure and can be changed as per the requirement of the
application.
3.2.2 RTC_MINUTES
This macro is used to initialize the minutes value in the clock structure and can be changed as per the requirement of the
application.
3.2.3 RTC_SECONDS
This macro is used to initialize the seconds value in the clock structure and can be changed as per the requirement of the
application.
3.2.4 RTCMOD_NORMAL_VALUE
This macro is used in Normal mode to load the RTCMOD register.
3.2.5 RTCMOD_LP_VALUE
This macro is used in Stop3 mode to load the RTCMOD register.
3.3 RTC_main.c
This file contains the main function, which acts as an application for the present RTC driver. This can be removed, when the
driver is integrated into the application.
3.3.1 System_Init
This API initializes the overall system. It disables the watchdog and enables the Stop3 mode only when the ignition is
stopped and is captured through the IRQ, and Low Voltage Detect (LVD) reset is disabled.
Syntax
void System_Init(void)
Parameters
None
Return Value
None
