bit 7
Legend:
R = Readable bit
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
-n = Value at POR
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
bit 13
Unimplemented: Read as ‘0’
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
bit 6
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 is enabled
0= Gated time accumulation is disabled
bit 5-4
bit 3
TCKPS<1:0>: Timerx Input Clock Prescale Select bits
11= 1:256
10= 1:64
01= 1:8
00= 1:1
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
bit 1
Unimplemented: Read as ‘0’
TCS: Timerx Clock Source Select bit(2)
1= External clock from pin, TxCK (on the rising edge)
0= Internal clock (FOSC/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)”.
3: Changing the value of TxCON while the timer is running (TON = 1) causes the timer prescale counter to
reset and is not recommended.
