DAP_UART_Control

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.
