Register 93: Universal Asynchronous Receiver/Transmitter Run Mode Clock
Gating Control (RCGCUART), offset 0x618
The RCGCUART register provides software the capability to enable and disable the UART modules
in Run mode. When enabled, a module is provided a clock and accesses to module registers are
allowed. When disabled, the clock is disabled to save power and accesses to module registers
generate a bus fault.
Important: This register should be used to control the clocking for 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.
