R = Readable bit
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

TON: Timery On bit
(1)
1
= Starts 16-bit Timery
0
= Stops 16-bit Timery
bit 14
Unimplemented: Read as ‘0’
bit 13
TSIDL: Stop in Idle Mode bit
(1)
1
= Discontinue module operation when device enters Idle mode
0
= Continue module operation in Idle mode

TGATE: Timery Gated Time Accumulation Enable bit
(1)
When TCS = 1:
This bit is ignored.
When TCS = 0:
1
This bit is ignored.
When TCS = 0:
1
= Gated time accumulation enabled
0
= Gated time accumulation disabled

Note 1:
When 32-bit operation is enabled (T2CON<3> or T4CON<3> = 1), these bits have no effect on Timery
operation; all timer functions are set through T2CON and T4CON.
operation; all timer functions are set through T2CON and T4CON.
2:
If TCS = 1, RPINRx (TxCK) must be configured to an available RPn/RPIn pin. See Section 10.4 “Peripheral
Pin Select (PPS)” for more information.
Pin Select (PPS)” for more information.
3:
Changing the value of TyCON while the timer is running (TON = 1) causes the timer prescale counter to
reset and is not recommended.
