Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

PWCEN: Power Control Enable bit
1 = Power control is enabled
0 = Power control is disabled
PWCPOL: Power Control Polarity bit
1 = Power control output is active-high
0 = Power control output is active-low
PWCCPRE: Power Control/Stability Prescaler bits
1 = PWC stability window clock is divide-by-2 of source RTCC clock
0 = PWC stability window clock is divide-by-1 of source RTCC clock
PWCSPRE: Power Control Sample Prescaler bits
1 = PWC sample window clock is divide-by-2 of source RTCC clock
0 = PWC sample window clock is divide-by-1 of source RTCC clock
RTCCLK<1:0>: RTCC Clock Select bits⁽²⁾
Determines the source of the internal RTCC clock, which is used for all RTCC timer operations.
00 = External Secondary Oscillator (SOSC)
01 = Internal LPRC Oscillator
10 = External power line source – 50 Hz
11 = External power line source – 60 Hz
RTCOUT<1:0>: RTCC Output Select bits
Determines the source of the RTCC pin output.
00 = RTCC alarm pulse
01 = RTCC seconds clock
10 = RTCC clock
11 = Power control
Unimplemented: Read as ‘0’
Note 1: The RTCPWC register is only affected by a POR.
2: When a new value is written to these register bits, the Seconds Value register should also be written to
properly reset the clock prescalers in the RTCC.
