5.1.7 Bank0.Reg6 - Remote Infrared Config Register (RIR_CFG)
Power on default <7:0> = 0000,0000 binary
Bit Name Read/Write Description
7-6 SMPSEL<1:0> Read/Write
Sampling Mode Select. Select internal decoder
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.
5-4 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.
3-2 RXDMSL<1:0> Read/Write
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.
1 PRE_DIV Read/Write
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.
0 RXINV Read/Write
Receiving Signal Invert. Write to 1, Invert the receiving
signal.
