7.10 INFRARED MODE
NS16C2552/2752 also integrates an IrDA version 1.0 com-
patible infrared encoder and decoder. The infrared mode is
enabled by MCR[6]=1.
In the infrared mode, the SOUT idles at logic 0. During data
transmission, the encoder transmits a 3/16 bit wide pulse for
each logic 0. With shortened transmitter-on light pulse, power
saving is achieved.
On the receiving end, each light pulse detected translates to
a logic 0, active low (Figure 12.)
