P_PNB: Programming Pulse Number Coding.
Write to 1 causes programming pulse number coding to be selected. The code format is
defined as follows.
If the bit value is set to 0, then the high pulse will be transmitted/received. If the bit value
is set to 1, then no energy will be transmitted/received.
SMP_M - Sampling mode.
To choose receiver sampling mode.
Write to 0 causes T-period sampling to be used, so that the T-period is programmed
UART baud rate.
Write to 1 causes direct use of programmed baud rate to do over-sampling.
