Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-8 PWCSTAB<7:0>: Power Control Stability Window Timer bits
11111111 = Stability Window is 255 T
PWCCLK clock periods
11111110 = Stability Window is 254 T
PWCCLK clock periods
...
00000001 = Stability Window is 1 T
PWCCLK clock period
00000000 = No Stability Window; Sample Window starts when the alarm event triggers
bit 7-0 PWCSAMP<7:0>: Power Control Sample Window Timer bits
(2)
11111111 = Sample Window is always enabled, even when PWCEN = 0
11111110 = Sample Window is 254 T
PWCCLK clock periods
...
00000001 = Sample Window is 1 T
PWCCLK clock period
00000000 = No Sample Window
Note 1: A write to this register is only allowed when RTCWREN = 1.
2: The Sample Window always starts when the Stability Window timer expires, except when its initial value is 00h.
