ROM Code always configures the UART port to 115200 kbaud, 8-n-1 mode, and the XMODEM protocol is used to transfer the boot data.
Table 4-30 summarizes the UART pin configuration done by ROM code for UART host on port 0.
Device Pin | Module Signal | Pull Enable | Pull Direction | Driver Index | Rx En/Dis | Tx En/Dis | Pinmux Sel |
---|---|---|---|---|---|---|---|
UART0_TXD | UART0_TXD | Enable | Up | 0 | Disable | Enable | 0 |
UART0_RXD | UART0_RXD | Enable | Up | 0 | Enable | Disable | 0 |
