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
1
= Starts 16-bit Timer3
0
= Stops 16-bit Timer3
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:
Timer3 Gated Time Accumulation Enable bit
(

When TCS = 1:
This bit is ignored.
When TCS = 0:
1
This bit is ignored.
When TCS = 0:
1
= Gated time accumulation is enabled
0
= Gated time accumulation is disabled

Note 1:
When 32-bit operation is enabled (T2CON<3> = 1), these bits have no effect on Timer3 operation; all timer
functions are set through T2CON.
functions are set through T2CON.
