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 illustrates 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.
