To select a mode, set the UART_MDR1[2:0] MODE_SELECT bit field (see Table 12-83).
Value | Mode |
---|---|
0x0: | UART 16× mode |
0x1: | SIR mode |
0x2: | UART 16× auto-baud |
0x3: | UART 13× mode |
0x4: | MIR mode |
0x5: | FIR mode |
0x6: | CIR mode |
0x7: | Disable (default state) |
MODE_SELECT is effective when the module is in operational mode (see Section 12.1.6.3.7.1, Register Access Modes).
To select a RS-485 mode, set the UART_MDR3[4] DIR_EN bit field to 0x1.
