4.2.70 SRUART Register (Offset = 0x518) [reset = 0x00]
Universal Asynchronous Receiver/Transmitter Software Reset (SRUART)
The SRUART register lets software reset the available UART modules.
A peripheral is reset by software using a simple 2-step process:
- Software sets a bit (or bits) in the SRUART register. While the SRUART bit is 1, the peripheral is held in reset.
- 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.
NOTE
Use this register to reset the UART modules.
SRUART is shown in Figure 4-76 and described in Table 4-83.
