Stellaris^® LM3S5P36 Microcontroller
Register 11: PWM Enable Update (PWMENUPD), offset 0x028
This register specifies when updates to the PWMnEN bit in the PWMENABLE register are performed.
The PWMnEN bit enables the pwmA' or pwmB' output to be passed to the microcontroller's pin.
Updates can be immediate or locally or globally synchronized to the next synchronous update.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
PWM5 Enable Update Mode
Value Description
0x0 Immediate
Writes to the PWM5EN bit in the PWMENABLE register are used
by the PWM generator immediately.
0x1 Reserved
0x2 Locally Synchronized
Writes to the PWM5EN bit in the PWMENABLE register are used
by the PWM generator the next time the counter is 0.
0x3 Globally Synchronized
Writes to the PWM5EN 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.
