Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

TMR3CS<1:0>: Clock Source Select bits
11 = Low-Power RC Oscillator (LPRC)
10 = External clock source (selected by T3CON<3>)
01 = Instruction clock (FOSC/2)
00 = System clock (FOSC)⁽¹⁾
T3CKPS<1:0>: Timer3 Input Clock Prescale Select bits
11 = 1:8 Prescale value
10 = 1:4 Prescale value
01 = 1:2 Prescale value
00 = 1:1 Prescale value
T3OSCEN: Timer Oscillator Enable bit
1 = SOSC (Secondary Oscillator) is used as a clock source
0 = T3CK digital input pin is used as a clock source
T3SYNC: External Clock Input Synchronization Control bit
When TMR3CS<1:0> = 1x:
1 = Do not synchronize the external clock input
0 = Synchronize the external clock input⁽²⁾
When TMR3CS<1:0> = 0x:
This bit is ignored; Timer3 uses the internal clock.
Unimplemented: Read as ‘0’
TMR3ON: Timer On bit
1 = Enables Timer
0 = Stops Timer
Note 1: The FOSC clock source should not be selected if the timer will be used with the ECCP Capture or Compare
features.
2: This option must be selected when the timer will be used with ECCP/CCP.
