Description
PWM3 Enable Update Mode
Value Description
0x0 Immediate
Writes to the PWM3EN bit in the PWMENABLE register are used
by the PWM generator immediately.
0x1 Reserved
0x2 Locally Synchronized
Writes to the PWM3EN bit in the PWMENABLE register are used
by the PWM generator the next time the counter is 0.
0x3 Globally Synchronized
Writes to the PWM3EN bit in the PWMENABLE register are used
by the PWM generator the next time the counter is 0 after a
synchronous update has been requested through the PWM
Master Control (PWMCTL) register.
0
PWM2 Enable Update Mode
Value Description
0x0 Immediate
Writes to the PWM2EN bit in the PWMENABLE register are used
by the PWM generator immediately.
0x1 Reserved
0x2 Locally Synchronized
Writes to the PWM2EN bit in the PWMENABLE register are used
by the PWM generator the next time the counter is 0.
0x3 Globally Synchronized
Writes to the PWM2EN bit in the PWMENABLE register are used
by the PWM generator the next time the counter is 0 after a
synchronous update has been requested through the PWM
Master Control (PWMCTL) register.
0
PWM1 Enable Update Mode
Value Description
0x0 Immediate
Writes to the PWM1EN bit in the PWMENABLE register are used
by the PWM generator immediately.
0x1 Reserved
0x2 Locally Synchronized
Writes to the PWM1EN bit in the PWMENABLE register are used
by the PWM generator the next time the counter is 0.
0x3 Globally Synchronized
Writes to the PWM1EN bit in the PWMENABLE register are used
by the PWM generator the next time the counter is 0 after a
synchronous update has been requested through the PWM
Master Control (PWMCTL) register.
