IrDA Mode
IrDA Modulation
The USART features an IrDA mode, supporting asynchronous, half-duplex, point-to-point wire-
less communication. It embeds the modulator and demodulator, allowing for a glueless
connection to the infrared transceivers, as shown in
enables this mode, and activates the IrDA specification v1.1 compliant modem. Data transfer
speeds ranging from 2.4Kbit/s to 115.2Kbit/s are supported and the character format is fixed to
one start bit, eight data bits, and one stop bit.
Figure 25-32. Connection to IrDA Transceivers
The receiver and the transmitter must be exclusively enabled or disabled, according to the direc-
tion of the transmission. To receive IrDA signals, the following needs to be done:
The RZI modulation scheme is used, where a zero is represented by a light pulse one 3/16
a bit period, and no pulse to represent a one. Some examples of signal pulse duration are
shown in
