bit 7 bit 0
bit 15 TON: Timer On bit
1 = Starts 16-bit TMRx
0 = Stops 16-bit TMRx
bit 14 Unimplemented: Read as ‘0’
bit 13 TSIDL: Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
bit 12-7 Unimplemented: Read as ‘0’
bit 6 TGATE: Timer Gated Time Accumulation Enable bit
1 = Timer gated time accumulation enabled
0 = Timer gated time accumulation disabled (Read as ‘0’ if TCS = 1)
(TCS must be set to logic ‘0’ when TGATE = 1)
bit 5-4 TCKPS<1:0>: Timer 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
bit 3-2 Unimplemented: Read as ‘0’
bit 1 TCS: Timer Clock Source Select bit
1 = External clock from pin TxCK
0 = Internal clock (F
OSC/4)
bit 0 Unimplemented: Read as ‘0’
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
