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

TON: Timerx On bit
When T32 = 1 (in 32-bit Timer mode):
1 = Starts 32-bit TMRx:TMRy timer pair
0 = Stops 32-bit TMRx:TMRy timer pair
When T32 = 0 (in 16-bit Timer mode):
1 = Starts 16-bit timer
0 = Stops 16-bit timer
Unimplemented: Read as ‘0’
TSIDL: Stop in Idle Mode bit
1 = Discontinue timer operation when device enters Idle mode
0 = Continue timer operation in Idle mode
Unimplemented: Read as ‘0’
TGATE: Timerx Gated Time Accumulation Enable bit
When TCS = 1:
This bit is ignored.
When TCS = 0:
1 = Gated time accumulation enabled
0 = Gated time accumulation disabled
TCKPS<1:0>: Timerx Input Clock Prescale Select bits
11 = 1:256 prescale value
10 = 1:64 prescale value
01 = 1:8 prescale value
00 = 1:1 prescale value
T32: 32-bit Timerx Mode Select bit
1 = TMRx and TMRy form a 32-bit timer
0 = TMRx and TMRy form separate 16-bit timer
Unimplemented: Read as ‘0’
TCS: Timerx Clock Source Select bit
1 = External clock from TxCK pin
0 = Internal clock (FOSC/2)
Unimplemented: Read as ‘0’
