12.10.1 RTC Calibration Control Register (RTCCOMR)
MC68HC908LJ24/LK24 — Rev. 2.1
Freescale Semiconductor
NOTE:
* CAL, AUTOCAL, and OUTF{1:0] bits are write-protected; unprotect by a write sequence to RTCWE[1:0].
Address:
The RTC calibration control register (RTCCOMR) contains control bits
for RTC calibration, output option for the CALOUT pin, and registers/bits
write-protect enable.
CAL — RTC Calibration Mode
AUTOCAL — RTC Automatic Calibration Enable
RTC clock and calendar functions are not affected when calibration is
enabled.
Reset:
Read:
Write:
This read/write bit enables the RTC calibration circuit. The CAL bit is
cleared automatically after completion of automatic calibration if
AUTOCAL is also set when CAL bit is set.
This read/write bit enables the CALIN pin to accept an incoming
1-Hz signal and calibration circuits for RTC automatic calibration. This
bit can only be set when the CAL bit is set. After calibration (approx.
15 seconds), the AUTOCAL bit is automatically cleared.
