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
bit 7-2
bit 1
Unimplemented: Read as ‘0’
T1GSS: Timer1 Gate Source Select bit(1)
1= Timer1 Gate Source is T1G pin (pin should be configured as digital input)
0= Timer1 Gate Source is comparator output
bit 0
CMSYNC: Comparator Output Synchronization bit(2)
1= Output is synchronized with falling edge of Timer1 clock
0= Output is asynchronous
Note 1: Refer to Section 6.6 “Timer1 Gate”.
2: Refer to Figure 7-2.
