Description
0: 32K clock buffer off (OUT_32K)
1: 32K clock buffer enabled (OUT_32K),
when powering up with a power sequence
including EN32K_STEP the buffer is enabled
when reaching EN32K_STEP, in case the
power sequence includes PD_DIS_STEP
with OUT_32K_PAUSE asserted the buffer
enable is delayed until reaching
PD_DIS_STEP on the way up
Note: with OUT_CLOCK being asserted the
buffer enable is delayed until 32K oscillator
signal is stable
0: No gating of RTC calendar clock
1: Clock to RTC counter is gated until 32K
oscillator stabilisation timer has expired
0: No gating of OUT_32K and clock signals
at GP_FB3
1: Clock to buffers is gated until 32K
oscillation stabilisation timer has expired
(indicating stable 32K oscillator signal)
0: Start stabilisation timer when duty
cycle of oscillator signal is in between
30% and 70%
1: Start stabilisation timer when CRYSTAL is
asserted, RTC_EN changed or when leaving
DELIVERY/NO-POWER mode with
CRYSTAL asserted
0: No 32 kHz crystal connected (bypass via
XOUT)
1: 32 kHz crystal connected
