Length Byte of the Received Packet during fixpklen = 0 .
(Specifies the number of Data bytes in the last received packet) This will be relevant
ONLY if fixpklen (address 33h, bit[3]) is low during the receive time. If fixpklen is high,
then the number of received Data Bytes can be read from the pklen register (address
h3E).
