LP_SL<1:0>
Read/Write
Low pass filter source selcetion.
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.

Description
7
RXACT
Read/Write
Receive Active. Set to 1 whenever a pulse or pulse-train is
detected by the receiver. If a 1 is written into the bit
position, the bit is cleared and the receiver is de-actived.
When this bit is set, the receiver samples the IR input
continuously at the programmed baud rate and transfers
the data to the receiver FIFO.
6
RX_PD
Read Only
Set to 1 whenever a pulse or pulse-train (modulated pulse)
is detected by the receiver. Can be used by the sofware to
detect idle condition Cleared Upon Read.

FOLVAL
Read Only
FIFO Level Value. Indicate that how many bytes are there
in the current received FIFO. Can read these bits then get
the FIFO level value and successively read RBR by the
prior value.
