PWM Registers
There are eleven registers dedicated to PWM operation. Each of these registers are covered in this section and summarized in
Table 124.
PWM Control Register [0xC0E6] [R/W]
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 Table 126.
