Demodulated data
Transmission data
TXD0 pin
SIO0
Support for IrDA
(1) Modulation of the transmission data
(2) Demodulation of the receive data
(3) Data format
SIO0 includes support for the IrDA 1.0 infrared data communication specification.
Figure 3.9.30 shows the block diagram.
Transmisison data
1/16 times for width of baud rate. The pulse width is selected by the SIRCR<PLSEL>.
When the transmit data is 1, the modem outputs 0.
Otherwise the modem outputs 1 to SIO0. The effective pulse width is selected by
SIRCR<SIRWD3:0>.
Receive data
When the transmit data is 0, the modem outputs 1 to TXD0 pin with either 3/16 or
When the receive data is the effective width of pulse 1, the modem outputs 0 to SIO0.
The data format is fixed as follows:

Data length: 8 bits
Parity bits: none
Stop bits: 1
