8.3.1 Bit Length Register (BLR)
This register is both a read and a write register.
It determines the length of the bit in terms of clock cycles.
The bit length will be (BLR+6) clocks, since the minimum length of a bit is 6 clocks.
Default Value: 00 (0+6=6).
8.3.2 Preamble Low Register (PRE-L)
This register is a write-only register.
This register contains the 8 least significant bits of the Preamble.
