When the PWM period is 2
The following requirements must be met when PWM mode is used.
PWM output to High . To start PWM output by modifying only the PWM period from this
state, PWM mode must be disabled once to modify the setting.
PWM period
T256
The following describes PWM minimum resolutions and duty.
The initial value of PWM output is always Low output. Duty 0% is always Low output,
Timer0Compare1 = 0x00: Duty = 0/255
Timer0Compare1 = 0x01: Duty = 1/255
Timer0Compare1 = 0xFE: Duty = 254/255
Timer0Compare1 = 0xFF: Duty = 255/255
