Encoding Scheme
The encoder sends a pulse for
every space or “0” that is sent on
the TXD line. On a high to low
transition of the TXD line, the
generation of the pulse is delayed
Decoding Scheme
3
A high to low transition of the
IR_RXD line from the infrared
transceiver module signifies a 3/
16th pulse. This pulse is
stretched to accommodate 1 bit
time (16 clock cycles). Every

for 7 clock cycles of the 16XCLK
before the pulse is set high for 3
clock cycles (or 3/16th of a bit
time) and then subsequently
pulled low.
pulse that is received is translated
into a “0” or space on the RXD
line equal to 1 bit time.
Note: The stretched pulse must
be at least 3/4 of a bit time in
duration to be correctly
interpreted by a UART.
