Write:
PWM control register 1 controls PWM enabling/disabling, the loading of
new modulus, prescaler, and PWM values, and the PWM correction
method. In addition, this register contains the software disable bits to
force the PWM outputs to their inactive states (according to the disable
mapping register).
DISX — Software Disable for Bank X Bit
DISY — Software Disable for Bank Y Bit
PWMINT — PWM Interrupt Enable Bit
dress:
Pulse-Width Modulator for Motor Control (PWMMC)
Ad-
This read/write bit allows the user to disable one or more PWM pins
in bank X. The pins that are disabled are determined by the disable
mapping write-once register.
This read/write bit allows the user to disable one or more PWM pins
in bank Y. The pins that are disabled are determined by the disable
mapping write-once register.
This read/write bit allows the user to enable and disable PWM CPU
interrupts. If set, a CPU interrupt will be pending when the PWMF flag
is set.
1 = Disable PWM pins in bank X
0 = Re-enable PWM pins at beginning of next PWM cycle
1 = Disable PWM pins in Bank Y Bit
0 = Re-enable PWM pins at beginning of next PWM cycle
1 = Enable PWM CPU interrupts
0 = Disable PWM CPU interrupts
