4.3.2 Configure Output Channels
The following CAN message also configures the outputs in two groups.
Configure Output Channels is a message sent to the PDM to set up the high-current output channels as a single
high-side output or as an H-bridge pair. It also sets the current limit and reset behavior. Depending on the
output configuration identifier, the message applies to either output channels 1-6 or 7-12 respectively.
Note: When channels are set to H-bridge pair, they are paired
consecutively (i.e. 1 and 2, 3 and 4, etc.).
