3.2.2 UART with Hardware Flow Control (RTS/CTS)
For an Application where the ADC is not in use, SERCOM0 can be multiplexed as shown in the following table.
| Module Pin | MCU Function | MCU Pin | Port and SERCOM Configuration |
|---|---|---|---|
| 14 | UART TX | 15 | SERCOM0; MUX=C; PAD[0] TXPO=0x2 |
| 25 | UART RX | 10 | SERCOM0; MUX=D; PAD[1] RXPO=0x1 |
| 26 | UART RTS | 11 | SERCOM0; MUX=D; PAD[2] TXPO=0x2 |
| 13 | UART CTS | 12 | SERCOM0; MUX=D; PAD[3] TXPO=0x2 |
The signals in this table are not available as module IO. For more information about the FLASH IC, see its related datasheet ([ADESTO]).
