Physical Address
Instance
Description
RTC compensation register (LSB)
Notes: This register must be written in 2-complement.
This means that to add one 32kHz oscillator period every hour, micro-controller needs to write FFFF into
RTC_COMP_MSB_REG & RTC_COMP_LSB_REG.
To remove one 32-kHz oscillator period every hour, micro-controller needs to write 0001 into
RTC_COMP_MSB_REG & RTC_COMP_LSB_REG.
The 7FFF value is forbidden.
