TnM1 and TnM0: Timer Clock Mode Select Bits.
Bits used to select the Timer clock source. The sources can be the System Clock
(SYSCLK), SYSCLK divided by 2 or 12, or an external clock signal routed to Tn (port pin)
divided by 8. Clock source is selected as follows:
00: SYSCLK/12
01: SYSCLK
10: EXTERNAL CLOCK/8
11: SYSCLK/2
TOGn: Toggle output state bit.
When timer is used to toggle a port pin, this bit can be used to read the state of the output, or
can be written to in order to force the state of the output.
TnOE: Timer output enable bit.
This bit enables the timer to output a 50% duty cycle output to the timer’s assigned external
port pin.
NOTE: A timer is configured for Square Wave Output as follows:
CP/RLn = 0
C/Tn
TnOE = 1
Load RCAPnH:RCAPnL (See “Toggle Mode Square Wave Frequency” on page 298.)
Configure Port Pin to output squarewave (See
0: Output of toggle mode not available at Timers’s assigned port pin.
1: Output of toggle mode available at Timers’s assigned port pin.
DCENn: Decrement Enable Bit.
This bit enables the timer to count up or down as determined by the state of TnEX.
0: Timer will count up, regardless of the state of TnEX.
1: Timer will count up or down depending on the state of TnEX as follows:

= 0
if TnEX = 0, the timer counts DOWN
if TnEX = 1, the timer counts UP.
