bit 7 bit 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
bit 15 TON: Timerx On bit
When TxCON<3> =
1:
1 = Starts 32-bit Timerx/y
0 = Stops 32-bit Timerx/y
When TxCON<3> =
0:
1 = Starts 16-bit Timerx
0 = Stops 16-bit Timerx
bit 14 Unimplemented: Read as ‘0
bit 13 TSIDL: Timerx Stop in Idle Mode bit
1 = Discontinues module operation when device enters Idle mode
0 = Continues module operation in Idle mode
bit 12-7 Unimplemented: Read as ‘0
bit 6 TGATE: Timerx Gated Time Accumulation Enable bit
When TCS = 1:
This bit is ignored.
When TCS =
0:
1 = Gated time accumulation is enabled
0 = Gated time accumulation is disabled
bit 5-4 TCKPS<1:0>: Timerx Input Clock Prescale Select bits
11 = 1:256
10 = 1:64
01 = 1:8
00 = 1:1
bit 3 T32: 32-Bit Timer Mode Select bit
(1)
1 = Timerx and Timery form a single 32-bit timer
0 = Timerx and Timery act as two 16-bit timers
In 32-bit mode, T3CON control bits do not affect 32-bit timer operation.
bit 2 Unimplemented: Read as ‘0
bit 1 TCS: Timerx Clock Source Select bit
(2)
1 = External clock from pin, TxCK (on the rising edge)
0 = Internal clock (F
OSC/2)
bit 0 Unimplemented: Read as ‘0
Note 1: In 32-bit mode, the T3CON or T5CON control bits do not affect 32-bit timer operation.
2: If TCS = 1, RPINRx (TxCK) must be configured to an available RPn pin. For more information, see
Section 10.4 “Peripheral Pin Select (PPS)”.
