RTC_C in Calendar mode, Interruptions every 1s, 1m, and 5th day of week at 5:00pm

This program demonstrates the RTC mode by triggering an interrupt every second and minute. This code toggles P1.0 every second. This code recommends an external LFXT1 crystal for RTC accuracy. Note that if XT1 is not present the code loops in an infinite loop. ACLK = LFXT1 = 32768Hz, MCLK = SMCLK = default DCO = 32 x ACLK = 1048576Hz

Tested On: MSP430FR6989

This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:

• RTC peripheral
• CS peripheral
• GPIO Port peripheral

This example uses the following interrupt handlers. To use this example in your own application you must add these interrupt handlers to your vector table.

• RTC_VECTOR
