Transmission data
TXD0 pin
Demodulated data
Receive pulse
<RXSEL> = “0”
Receive pulse
<RXSEL> = “1”
SIO0
Support for IrDA
(1) Modulation of the transmission data
(2) Demodulation of the receive data
SIO0 includes support for the IrDA 1.0 infrared data communication specification.
Figure 3.9.24 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 transfer data is 1, the modem outputs 0.
the modem outputs 0 to SIO0. Otherwise the modem outputs 1 to SIO0. The receive
pulse logic is also selectable by SIRCR<RXSEL>.
Receive data
When the transfer data is 0, the modem outputs 1 to TXD0 pin with either 3/16 or
When the receive data has the effective high level pulse width (Software selectable),
