Note 2: The set value of timer register must satisfy the following conditions.
(a) When in PWM output mode, 5
(b) When in any other mode than PWM output mode, 0< TREG5
Note 3: Source clock fcl22, fcl2, and fc cannot be used except in PWM output mode.
Note 4: Set the operating mode and the source clock selection when timer/counter stops (TC5S = 0).
