Type Definitions

PREDIV_A_R

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

PREDIV_A_W

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

PREDIV_S_R

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

PREDIV_S_W

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