Description
Crystal Oscillator Control
Controls the operation of the crystal oscillator for the
RTC.
0: Halts the crystal oscillator for the RTC.
1: Runs the crystal oscillator for the RTC.
30-Second Adjustment
When 1 is written to the ADJ bit, times of 29 seconds or
less will be rounded to 00 seconds and 30 seconds or
more to 1 minute. The divider circuit (RTC prescaler
and R64CNT) will be simultaneously reset. This bit
always reads 0.
Important: When using this bit, see section 15.5.5,
Procedure for Setting the 30-Second Adjustment
Function.
0: Runs normally.
1: 30-second adjustment.
Reset
Writing 1 to this bit initializes the divider circuit. In this
case, the RESET bit is automatically reset to 0 after 1 is
written to and the divider circuit (RTC prescaler and
R64CNT) is reset. Thus, there is no need to write 1 to
this bit. This bit is always read as 0.
0: Runs normally.
1: Divider circuit is reset.
Start Bit
Halts and restarts the counter (clock).
0: Second/minute/hour/day/week/month/year counter
1: Second/minute/hour/day/week/month/year counter
Note: The 64-Hz counter always runs unless stopped
halts.
