Description
Length of preamble in bytes. Example: a value of decimal 3 results in a
preamble of 24 bits.
Description
Lower byte of CRC_POLY[15:0], which sets the CRC polynomial. See Table 81.
Description
Upper byte of CRC_POLY[15:0], which sets the CRC polynomial. See the
Packet Mode section for more details on how to configure a CRC polynomial.
