B.42.2.3 MSPDS UART Backchannel Activation Commands
The MSP-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 B-44 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: 3.3-V target V
CC
, no flow control mechanism.
Table B-44. UART Backchannel 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 Configure backchannel UART communication with handshake
9623 Voltage configuration command.
When this command is received, target V
CC
is set to 3300 mV. After target V
CC
is configured, it is switched
through to the target device.
