5.12.18.2 UART IrDA Interface

The IrDA module operates in three different modes:

•

Slow infrared (SIR) (

≤ 115.2 Kbps)

•

Medium infrared (MIR) (0.576 Mbps and 1.152 Mbps)

•

Fast infrared (FIR) (4 Mbps).

Figure 5-145 illustrates the UART IrDA pulse parameters. Table 5-133 and Table 5-134 list the signaling rates

and pulse durations for UART IrDA receive and transmit modes.
