Description
Run Length Control. When set to 1, this bit enables run length encoding/decoding. The
format of a run length code is:
Yxxxxxxx, where Y is the bit value and xxxxxxx is the number of bits minus 1 (selects
from 1 to 128 bits).
Receiver Sampling Mode.
0: Programmed T period sampling.
1: Oversampling mode.
Receiver Carrier Frequency Select. This bit selects the receiver demodulator fre-
quency range.
0: Low frequency: 30.0-56.9 kHz.
1: High frequency: 400-480 kHz.
Receiver Demodulation Disable. When this bit is 1, the internal demodulator is dis-
abled. The internal demodulator, when enabled, performs carrier frequency checking and
envelope generation. This bit must be set to 1 (disabled) when the demodulation is per-
formed externally, or when oversampling mode is selected to determine the carrier fre-
quency.
Reserved. Write as 0.
Transmitter Subcarrier Frequency Select. This bit selects the modulation carrier fre-
quency range.
0: Low frequency: 30.0-56.9 kHz.
1: High frequency: 400-480 kHz.
Transmitter Modulator Mode. Determines how IR pulses are generated from the trans-
mitted bit string.
00: C_PLS modulation mode. Pulses are generated continuously for the entire logic 0 bit
01: 8_PLS modulation mode. 8 pulses are generated each time one or more logic 0 bits
10: 6_PLS Modulation Mode. 6 pulses are generated each time one or more logic 0 bits
11: Reserved. Result is indeterminate.
