R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets

NxEN: NCOx Enable bit
1 = NCOx module is enabled
0 = NCOx module is disabled
NxOE: NCOx Output Enable bit
1 = NCOx output pin is enabled
0 = NCOx output pin is disabled
NxOUT: NCOx Output bit
1 = NCOx output is high
0 = NCOx output is low
NxPOL: NCOx Polarity bit
1 = NCOx output signal is active low (inverted)
0 = NCOx output signal is active high (non-inverted)
Unimplemented: Read as ‘0’
NxPFM: NCOx Pulse Frequency Mode bit
1 = NCOx operates in Pulse Frequency mode
0 = NCOx operates in Fixed Duty Cycle mode

NxPWS<2:0>: NCOx Output Pulse Width Select bits(1, 2)
111 = 128 NCOx clock periods
110 = 64 NCOx clock periods
101 = 32 NCOx clock periods
100 = 16 NCOx clock periods
011 = 8 NCOx clock periods
010 = 4 NCOx clock periods
001 = 2 NCOx clock periods
000 = 1 NCOx clock periods
Unimplemented: Read as ‘0’
NxCKS<1:0>: NCOx Clock Source Select bits
11 = NCO1CLK pin
10 = LC1_out
01 = FOSC
00 = HFINTOSC (16 MHz)
Note 1: NxPWS applies only when operating in Pulse Frequency mode.
2: If NCOx pulse width is greater than NCO_overflow period, operation is indeterminate.
