Description
Location of data for read/write RTC operation.
Description
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).
Description
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).

Result
The RTC register at RTC_ADDRESS (Bits[4:0]) is read into the RTCDAT SFR
(Address 0xA4).
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.
