00 = PWM time base input clock period is TCY (1:1 prescale)
PTMOD<1:0>: PWM Time Base Mode Select bits
11 = PWM time base operates in a Continuous Up/Down Count mode with interrupts for double
PWM updates
10 = PWM time base operates in a Continuous Up/Down Count mode
01 = PWM time base operates in Single Pulse mode
00 = PWM time base operates in a Free-Running mode
