Sampling
methodology from the internal filter. Selected decoder
mode will determine the receive data format. The
sampling mode is shown as bellow:
SMPSEL<1:0> = 00 T-Period Sample Mode.
SMPSEL<1:0> = 01 Over-Sampling Mode.
SMPSEL<1:0> = 10 Over-Sampling with re-sync.
SMPSEL<1:0> = 11 FIFO Test Mode.
The T-period code format is defined as follows.
The Bit value is set to 0, then the high pulse will be
received. The Bit value is set to 1, then no energy will
be received. The opposite results will be generated
when the bit RXINV (Bank0.Reg6.Bit0) is set to 1.
Low pass filter source selection.
LP_SL<1:0> = 00 Select raw IRRX signal.
LP_SL<1:0> = 01 Select R.B.P. signal
LP_SL<1:0> = 10 Select D.B.P. signal.
LP_SL<1:0> = 11 Reserved.
Receiver Demodulation Source Selection.
RXDMSL<1:0> = 00 select B.P. and L.P. filter.
RXDMSL<1:0> = 01 select B.P. but not L.P.
RXDMSL<1:0> = 10 Reserved.
RXDMSL<1:0> = 11 do not pass demodulation.
Baud Rate Pre-divisor. Set to 1, the baud rate generator
input clock is set to 1.8432M Hz which is set to pre-
divisor into 13. When set to 0, the pre-divisor is set to 1,
that is, the input clock of baud rate generator is set to
24M Hz.
Receiving Signal Invert. Write to 1, Invert the receiving
signal.
