12.2.3.2 MMUART Reset
MMUART resets to zero on power-up and is held in reset until it is enabled. An option is provided under software control to reset the MMUART by writing to bit 7 or bit 8 of the SOFT_RESET_CR, located in the SYSREG block. At power-up, the reset signals are asserted 1. This keeps MMUART peripherals in a reset state. MMUART peripheral becomes active when the bit is set to 0, as mentioned in the following table.
| Bit Number | Name | R/W | Reset Value | Description |
|---|---|---|---|---|
| 8 | MMUART1_SOFTRESET | R/W | 0x1 | Controls reset input to MMUART_1 0: Release MMUART_1 from reset 1: Keep MMUART_1 in reset (reset value) |
| 7 | MMUART0_SOFTRESET | R/W | 0x1 | Controls reset input to MMUART_0 0: Release MMUART_0 from reset 1: Keep MMUART_0 in reset (reset value) |
