Real-time clock (counts during stop mode)
RTC module can be clocked either from 32 kHz quartz, 4 MHz quartz or from the RC
Oscillator
Facility to correct oscillation deviation (subclock calibration)
Read/write accessible second/minute/ hour registers
Can signal interrupts every half second/second/ minute/hour/day
Internal clock divider and prescaler provide exact 1s clock based on a 4 MHz or a 32 kHz
clock input
Prescaler value for 4 MHz is 1E847FH
Prescaler value for 32 kHz is 003FFFH
Clock supervisor
Monitors external 32kHz and 4MHz for fails (e.g. crystal breaks)Switches in case of fail to
an available recovery clock (other oscillator, or RC oscillator)
Clock modulator
Reduction of Electro Magnetic Emission (EME)
Subclock calibration
Calibration of the RTC timer in 32 kHz or RC oscillator operation, based on the more
accurate 4 MHz quartz is possible
Main oscillation stabilization timer
23 bit counter for main oscillation stabilization wait when running in sub clock mode
Generates an interrupt when stabilization time has elapsed
Sub oscillation stabilization timer
15 bit counter for sub oscillation stabilization wait when running in main clock mode
Generates an interrupt when stabilization time has elapsed
