Table 130. RTC Pointer Address SFR (RTCPTR, Address 0xA3)
Bit Mnemonic Default Description
7 RTCW_RB 0 Read/write selection.
RTCW_RB
Result
0 The RTC register at RTC_ADDRESS (Bits[4:0]) is read into the RTCDAT SFR
(Address 0xA4).
1 The data in the RTCDAT SFR is written in the RTC register at RTC_ADDRESS
(Bits[4:0]). This operation is completed only if the KYREG SFR (Address 0xC1)
is set to 0xEA, the instruction before writing to the RTCDAT SFR.
[6:5] Reserved N/A Reserved.
[4:0] RTC_ADDRESS 0 Target address for read/write operation.
Table 131. RTC Pointer Data SFR (RTCDAT, Address 0xA4)
Bit Mnemonic Default Description
[7:0] RTC_DATA 0 Location of data for read/write RTC operation.
Table 132. RTC Nominal Compensation SFR (RTCCOMP, Address 0xF6)
Bit Mnemonic Default Description
[7:0] RTCCOMP 0 Holds the nominal RTC compensation value at 25°C. Note that this register is reset after a
watchdog reset, an external reset, or a power-on reset (POR).
Table 133. RTC Temperature Compensation SFR (TEMPCAL, Address 0xF7)
Bit Mnemonic Default Description
[7:0]
TEMPCAL
0
Calibrates the RTC over temperature. This allows the external crystal shift to be compensated
over temperature. Note that this register is reset after a watchdog reset, an external reset, or a
power-on reset (POR).
