STATUS - Real Time Counter Status Register
INTCTRL - Real Time Counter Interrupt Control Register
• Bits 7:1 - Reserved
These bits are reserved and will always be read as zero. For compatibility with future devices,
always write these bits to zero when this register is written.
• Bit 0 - SYNCBUSY: RTC Synchronization Busy Flag
This bit is set when the CNT, CTRL, PER or COMP register is busy synchronizing between the
RTC clock and system clock domains.
• Bits 7:4 - Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bits 3:2 - COMPINTLVL[1:0]: RTC Compare Match Interrupt Enable
These bits enable the RTC Compare Match Interrupt and select the interrupt level as described
in
enabled interrupt will trigger when the COMPIF in the INTFLAGS register is set.
• Bits 1:0 - OVFINTLVL[1:0]: RTC Overflow Interrupt Enable
These bits enable the RTC Overflow Interrupt and select the interrupt level as described in
tion 12. ”Interrupts and Programmable Multi-level Interrupt Controller” on page
interrupt will trigger when the OVFIF in the INTFLAGS register is set.
