Peripheral Information and Timings

7.15.2 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 7-115 shows the UART IrDA pulse parameters. Table 7-115 and Table 7-116 list the signaling

rates and pulse durations for UART IrDA receive and transmit modes.
