Packet Length.
The value in the pklen[7:0] register corresponds directly to the number of bytes
in the Packet. For example pklen[7:0] = ‗00001000‘ corresponds to a packet
length of 8 bytes. The maximum packet length is pklen[7:0] = ‗11111111‘, a 255
byte packet. Writing 0 is possible, in this case we do not send any data in the
packet. During RX, if fixpklen = 1, this will specify also the Packet Length for RX
mode.
