bit 3

T32: 32-Bit Timer Mode Select bit(3)

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

Unimplemented: Read as ‘0’

bit 1

TCS: Timerx Clock Source Select bit(2)

1 = Timer source is selected by TECS<1:0>

0 = Internal clock (FOSC/2)

bit 0

Unimplemented: Read as ‘0’

TxCON: TIMER2 CONTROL REGISTER(1) (CONTINUED)

Note 1:

Changing the value of TxCON while the timer is running (TON = 1) causes the timer prescale counter to

reset and is not recommended.

If TCS = 1 and TECS<1:0> = x1, the selected external timer input (TxCK or TyCK) must be configured to

an available RPn/RPIn pin. For more information, see Section 11.5 “Peripheral Pin Select (PPS)”.

In 32-bit mode, the T3CON control bits do not affect 32-bit timer operation.
