Description
The PWM Timer Counter and PWM Prescale Counter are
enabled for counting.
The counters are disabled.
The PWM Timer Counter and the PWM Prescale Counter
are synchronously reset on the next positive edge of PCLK.
The counters remain reset until this bit is returned to zero.
Clear reset.
Reserved, user software should not write ones to reserved
bits. The value read from a reserved bit is not defined.
PWM mode is enabled (counter resets to 1). PWM mode
causes the shadow registers to operate in connection with
the Match registers. A program write to a Match register will
not have an effect on the Match result until the
corresponding bit in PWMLER has been set, followed by the
occurrence of a PWM Match 0 event. Note that the PWM
Match register that determines the PWM rate (PWM Match
Register 0 - MR0) must be set up prior to the PWM being
enabled. Otherwise a Match event will not occur to cause
shadow register contents to become effective.
Timer mode is enabled (counter resets to 0).
The two PWMs may be synchronized using the Master
Disable control bit. The Master disable bit of the Master
PWM (PWM0 module) controls a secondary enable input to
both PWMs, as shown in
This bit has no function in the Slave PWM (PWM1).
PWM0 is the master, and both PWMs are enabled for
counting.
The PWM’s are used independently, and the individual
Counter Enable bits are used to control the PWM’s.
Reserved, user software should not write ones to reserved
bits. The value read from a reserved bit is not defined.
