Demodulated data
Support for IrDA
Figure 3.9.25 shows the block diagram.
(1) Modulation of the transmission data
Transmission data
TXD0 pin
(2) Demodulation of the receive data
SIO0 includes support for the IrDA 1.0 infrared data communication specification.
SIO0
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>.
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),
