Real Time Clock (RTC)
12.6.2 RTC Control Register 2 (RTCCR2)
Technical Data
218
Address:
The RTC control register 2 (RTCCR2) contains control and clock
selection bits for RTC operation.
CHRCLR — Chronograph counter clear
CHRE — Chronograph Enable
RTCE — Real Time Clock Enable
Reset:
Read:
Write:
Setting this write-only bit resets the chronograph counter. Setting
CHRCLR has no effect on any other registers. Counting resumes
from $00. CHRCLR is cleared automatically after the chronograph
counter is reset and always reads as logic 0. Reset clears the
CHRCLR bit.
This read/write bit enables the chronograph counter, the value in the
chronograph data register increments by 1 in every 1/100 seconds.
When the chronograph counter is disabled (CHRE = 0), the value in
the chronograph data register is held at the count value. Reset clears
the CHRE bit.
This read/write bit enables the entire RTC module, allowing all RTC
and chronograph operations. Disabling the RTC module does not
affect the contents in the RTC registers. Reset clears the RTCE bit.
1 = Chronograph counter cleared
0 = No effect
1 = Chronograph counter enabled
0 = Chronograph counter disabled
1 = RTC module enabled
0 = RTC module disabled
