Description
The TEMPCAL SFR is adjusted based on the temperature read in the TEMPADC SFR 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 the FSEL bits
is output on the P0.2/CF1/RTCCAL pin.
Sets RTC calibration output frequency and calibration window.

Description
The interval timer counts according to the time base established in the ITS bits of the RTC configuration SFR
(TIMECON, 0xA1). When 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
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.
Description
Write 0xA7 to this SFR before writing to the POWCON SFR, which unlocks KYREG.
Write 0xEA to this SFR before writing to the INTPR, HTHSEC, SEC, MIN, or HOUR timekeeping registers
to unlock KYREG.
