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
.
