4.2.91 RCGCUART Register (Offset = 0x618) [reset = 0x00]
Universal Asynchronous Receiver/Transmitter Run Mode Clock Gating Control (RCGCUART)
The RCGCUART register lets software 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.
NOTE
This register controls the clocking for the UART modules.
RCGCUART is shown in Figure 4-97 and described in Table 4-104.
