Description
The TEMPCAL SFR is adjusted based on the temperature read in the TEMPADC to calibrate the RTC over
temperature. This allows the external crystal shift to be compensated over temperature. This register is
retained during a watchdog reset or an external reset. It is reset after a POR.
Description
Controls the RTC calibration output. When set, the RTC calibration frequency selected by FSEL[1:0] is
output on the P0.2/CF1/RTCCAL pin.
Sets RTC calibration output frequency and calibration window.

Description
Write 0xA7 to the this SFR before writing to the POWCON SFR, which unlocks KYREG.
Write 0xEA to the this SFR before writing to the INTPR, HTHSEC, SEC, MIN, or HOUR timekeeping
registers to unlock KYREG.
Description
The interval timer counts according to the time base established in the ITS[1:0] bits of the RTC Configuration
SFR (TIMECON, 0xA1). Once the number of counts is equal to INTVAL, the ALARM flag is set and a
pending RTC interrupt is created. Note that the interval counter is eight bits. Therefore, it can count up to
255 seconds, for example.
Description
The RTCCOMP SFR holds the nominal RTC compensation value at 25°C. This register is retained during
a watchdog reset or an external reset. It is reset after a POR.
