Table 133. RTC Alarm Interval SFR (INTVAL, Address 0xA6)
Bit
[7:0]
Mnemonic
INTVAL
Default
0
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.
Table 134. RTC Nominal Compensation SFR (RTCCOMP, Address 0xF6)
Bit
[7:0]
Mnemonic
RTCCOMP
Default
0
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.
Table 135. RTC Temperature Compensation SFR (TEMPCAL, Address 0xF7)
Bit
[7:0]
Mnemonic
TEMPCAL
Default
0
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.
Table 136. Interrupt Pins Configuration SFR (INTPR, Address 0xFF)
Bit
7
Mnemonic
RTCCAL
Default
0
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.
[6:5]
FSEL
Sets RTC calibration output frequency and calibration window.

Table 137. Key SFR (KYREG, Address 0xC1)
Bit
[7:0]
Mnemonic
KYREG
Default
0
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.
