Register 111: Universal Asynchronous Receiver/Transmitter Peripheral Ready
(PRUART), offset 0xA18
The PRUART register indicates whether the UART modules are ready to be accessed by software
following a change in status of power, Run mode clocking, or reset. A Run mode clocking change
is initiated if the corresponding RCGCUART bit is changed. A reset change is initiated if the
corresponding SRUART bit is changed from 0 to 1.
The PRUART 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.
