Preamble Length.
The value in the prealen[8:0] register corresponds to the number of nibbles (4
bits) in the packet. For example prealen[8:0] = ‗000001000‘ corresponds to a
preamble length of 32 bits (8 x 4bits) or 4 bytes. The maximum preamble length
is prealen[8:0] = 111111111 which corresponds to a 255 bytes Preamble.
Writing 0 will have the same result as if writing 1, which corresponds to one
single nibble of preamble.
