A (7+1) bits mode PWM cycle is divided into two modu-
lation cycles (modulation cycle0~modulation cycle 1).
Each modulation cycle has 128 PWM input clock period.
In a (7+1) bits PWM function, the contents of the PWM
register is divided into two groups. Group 1 of the PWM
register is denoted by DC which is the value of
PWM.7~PWM.1. The group 2 is denoted by AC which is
the value of PWM.0.
In a (7+1) bits mode PWM cycle, the duty cycle of each
modulation cycle is shown in the table.
