System Control
Register 184: Pulse Width Modulator Peripheral Ready (PRPWM), offset 0xA40
The PRPWM register indicates whether the PWM modules are ready to be accessed by software
following a change in status of power, Run mode clocking, or reset. A power change is initiated if
the corresponding PCPWM bit is changed from 0 to 1. A Run mode clocking change is initiated if
the corresponding RCGCPWM bit is changed. A reset change is initiated if the corresponding
SRPWM bit is changed from 0 to 1.
The PRPWM bit is cleared on any of the above events and is not set again until the module is
completely powered, enabled, and internally reset.

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.
PWM Module 0 Peripheral Ready
Value Description
0 PWM module 0 is not ready for access. It is unclocked,
unpowered, or in the process of completing a reset sequence.
1 PWM module 0 is ready for access.
