P_PNB: Programming Pulse Number Coding.
Write a 1 to select programming pulse number coding. The code format is defined as
follows.
(Number of bits) - 1

Bit 3:
Bit 2:
If the bit value is set to 0, 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 select receiver sampling mode.
When set to 0 then uses T-period sampling, that the T-period is programmed IR baud
rate.
When set to 1, programmed baud rate will be used to do oversampling.
