PWM Control Register [0xC0E6] [R/W]
Table 125. PWM Control Register
Register Description
The PWM Control register provides high level control over all four
of the PWM channels.
PWM Enable (Bit 15)
The PWM Enable bit starts and stops PWM operation.
1: Start operation
0: Stop operation
Prescale Select (Bits [11:9])
The Prescale Select field sets the frequency of all the PWM
channels as defined in
