Legend:
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
bit 15
TON: Timer3 On bit
(2)
1 = Starts 16-bit Timer3
0 = Stops 16-bit Timer3
0 = Stops 16-bit Timer3
bit 14
Unimplemented: Read as ‘0’
bit 13
TSIDL: Stop in Idle Mode bit
(1)
1 = Discontinue timer operation when device enters Idle mode
0 = Continue timer operation in Idle mode
0 = Continue timer operation in Idle mode

3 Gated Time Accumulation Enable bit
(2)
When TCS = 1:
This bit is ignored.
When TCS = 0:
1 = Gated time accumulation enabled
0 = Gated time accumulation disabled
This bit is ignored.
When TCS = 0:
1 = Gated time accumulation enabled
0 = Gated time accumulation disabled

bit 0
Unimplemented: Read as ‘0’
Note 1: When 32-bit timer operation is enabled (T32 = 1) in the Timer Control register (T2CON<3>), the TSIDL bit
must be cleared to operate the 32-bit timer in Idle mode.
2: When the 32-bit timer operation is enabled (T32 = 1) in the Timer Control register (T2CON<3>), these bits
have no effect.
