PRODUCTION DATA
The number of data bytes and the relevant information they convey is determined by the type of command frame sent and the target register specified in that command frame. When part of a command frame, the data bytes contain the values to be written to the registers. When part of a response frame, the data bytes contain the values returned from the registers.

---|---|---|---|---|---|
