5.8.2.1 eZ-FET and eZ-FET Lite UART Backchannel Activation Commands
The eZ-FET supports two different backchannel UART modes, one with flow control and one without. The different modes can be selected by opening the corresponding COM port with a dedicated baud rate. See Table 15 for the specific baud rates for each command.
NOTE
The baud rates used by these commands cannot be used for communication.
If none of the specified commands are transferred before setting the communication baud rate, communication starts with these default settings: VCC on, no flow control mechanism, no parity.
Table 15. eZ-FET and eZ-FET Lite Backchannel UART Activation Commands
| Baud Rate |
Command |
| 9620 |
Set all backchannel UART pins to high impedance – no current flow into target device |
| 9621 |
Configure backchannel UART communication without handshake (default start behavior) |
| 9622 |
