T2M: Timer 2 Clock Select.
This bit controls the division of the system clock supplied to Timer 2. This bit is ignored
when the timer is in baud rate generator mode or counter mode (i.e. C/T2 = 1).
0: Timer 2 uses the system clock divided by 12.
1: Timer 2 uses the system clock.
T1M: Timer 1 Clock Select.
This bit controls the division of the system clock supplied to Timer 1.
0: Timer 1 uses the system clock divided by 12.
1: Timer 1 uses the system clock.
T0M: Timer 0 Clock Select.
This bit controls the division of the system clock supplied to Counter/Timer 0.
0: Counter/Timer uses the system clock divided by 12.
1: Counter/Timer uses the system clock.
