• Manufacturer: Freescale Semiconductor, Inc

Read: anytime
Write: anytime (any value written causes PWM counter to be reset to 0x0000).
12.3.2.13 PWM Channel Period Registers (PWMPERx)
There is a dedicated period register for each channel. The value in this register determines the period of
the associated PWM channel.
The period registers for each channel are double buffered so that if they change while the channel is
enabled, the change will NOT take effect until one of the following occurs:
Freescale Semiconductor
Module Base + 0x000E
Module Base + 0x000F
Module Base + 0x00010
Module Base + 0x00011
