Section 16 Realtime Clock (RTC)
Bit 2—30 Second Adjustment (ADJ): When the ADJ bit is written with 1, the time of 29
seconds or less will be rounded to 00 seconds and the time of 30 seconds or more to 1 minute. The
divider circuits (RTC prescaler and R64CNT) will be simultaneously reset. This bit is always read
as 0.
Bit 2: ADJ
0
1 (write)
Bit 1—Reset (RESET): When 1 is written to the RESET bit, the divider circuits (RTC prescaler
and R64CNT) are initialized. This bit is always read as 0.
Bit 1: RESET
0
1 (Write)
Bit 0—Start Bit (START): Halts and restarts the counter (clock).
Bit 0: START
0
1
Note: * The 64-Hz counter operates normally until it is stopped with the RTCEN bit.
