Description

This register must be written in initialization mode only. The initialization must be performed in two separate write accesses. Refer to Calendar initialization and configuration on page9.This register is write protected. The write access procedure is described in RTC register write protection on page9.

Fields

PREDIV_S

Synchronous prescaler factor This is the synchronous division factor: ck_spre frequency = ck_apre frequency/(PREDIV_S+1)
PREDIV_A

Asynchronous prescaler factor This is the asynchronous division factor: ck_apre frequency = RTCCLK frequency/(PREDIV_A+1)
