Register 74: Universal Asynchronous Receiver/Transmitter Software Reset
(SRUART), offset 0x518
The SRUART register provides software the capability to reset the available UART modules.
A peripheral is reset by software using a simple two-step process:
1. Software sets a bit (or bits) in the SRUART register. While the SRUART bit is 1, the peripheral
is held in reset.
2. Software completes the reset process by clearing the SRUART bit.
There may be latency from the clearing of the SRUART bit to when the peripheral is ready for use.
Software should check the corresponding PRUART bit to verify that the UART Module registers are
ready to be accessed.
Important: This register should be used to reset the UART modules.

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.
