RTC – Interrupt Registers
The interrupts for the RTC module can be controlled and monitored by writing 8-bit control words to the various registers
described below.
RTC_INT_CTL – RTC Interrupt Control Register
IC Address = Page-0: 79(0x4F), C Address = 0xA04F

RTC_INT_ST – RTC Interrupt Status Register
A logic ‘1’ in the A1_FLAG bit indicates that the time matched the value programmed into the registers for alarm 1. If the
A1_EN bit is set to a logic ‘1’ at the time the A1_FLAG goes to logic ‘1’, the INT pin will be asserted. The A1_FLAG is cleared
when a logic ‘1’ is written to this register location. This bit can only be written to logic ‘1’. Attempting to write a logic ‘0’ leaves
the value unchanged.
A logic ‘1’ in the A2_FLAG bit indicates that the time matched the value programmed into the registers for alarm 2. If the
A2_EN bit is set to a logic ‘1’ at the time the A2_FLAG goes to logic ‘1’, the INT pin will be asserted. The A2_FLAG is cleared
when a logic ‘1’ is written to this register location. This bit can only be written to logic ‘1’. Attempting to write a logic ‘0’ leaves
the value unchanged.
