The initial state of the CRC polynomial is state to all 1b in all cases.

Manchester coding

Manchester coding can be enabled for the Basic and STack packet formats only by setting to ‘1’ the

MANCHESTER_EN register.

Use of Manchester coding is exclusive with FEC and Three-out-of-six coding.

When Manchester coding is enabled each bit ‘1’ is actually transmitted on air as a ‘10’ sequence while a bit ‘0’ is

transmitted as a ‘01’ sequence. If enabled, Manchester encoding is applied to all bits following the SYNC word.
