Not all UART features are implemented in the on-board debugger CDC. The
constraints are outlined here:
- Baud rate: Must be in the
range 1200 bps to 500 kbps. Any baud rate outside this range will be set to the
closest limit, without warning. Baud rate can be changed on-the-fly.
- Character format: Only 8-bit
characters are supported.
- Parity: Can be odd, even, or
none.
- Hardware flow control: Not
supported.
- Stop bits: One or two bits are
supported.
