Register 1: Hibernation RTC Counter (HIBRTCC), offset 0x000
This register is the current 32-bit value of the RTC counter.
The RTC counter consists of a 32-bit seconds counter and a 15-bit sub seconds counter. The RTC
counters are reset by the Hibernation module reset. The RTC 32-bit seconds counter can be set by
the user using the HIBRTCLD register. When the 32-bit seconds counter is set, the 15-bit sub
second counter is cleared.
The RTC value can be read by first reading the HIBRTCC register, reading the RTCSSC field in the
HIBRTCSS register, and then rereading the HIBRTCC register. If the two values for HIBRTCC are
equal, the read is valid.
Note: There is a minimum system clock rate of three times the HIB clock rate to properly read the
HIBRTCC register.
