Control UART data receive and transmit.
DAP_UART_Control (0x22):
Enables and disables UART receive and transmit (only for transport via DAP).
DAP_UART_Control Request:
| BYTE | BYTE |
> 0x22 | Control |
|******|*********|
- Control:
- Bit 0: 1 = Receive Enable, 0 = no operation
- Bit 1: 1 = Receive Disable, 0 = no operation
- Bit 2: 1 = Receive Buffer Flush, 0 = no operation
- Bit 3: reserved (0)
- Bit 4: 1 = Transmit Enable, 0 = no operation
- Bit 5: 1 = Transmit Disable, 0 = no operation
- Bit 6: 1 = Transmit Buffer Flush, 0 = no operation
- Bit 7: reserved (0)
- Note
- DAP_UART_Control command can be used only if transport via DAP is enabled.
Receive/Transmit enable bit can be set only if DAP UART is already configured (DAP_UART_Configure).
-
When enable and disable bits are set at the same time, only disable is executed.
Receive/Transmit enable also automatically flushes any existing data in Receive/Transmit buffer.
