17.3 Register Description
The IrDA has the following internal registers. For details on register addresses and register states
in each processing state, refer to section 24, List of Registers.
• IrDA mode register (SCSMR_Ir)
17.3.1 IrDA Mode Register (SCSMR_Ir)
SCSMR_Ir is a 16-bit register that selects IrDA or SCIF mode and selects the IrDA output pulse
width.
This module operates as IrDA when the IRMOD bit is set to 1. When the IRMOD bit is cleared to
0, this module can also operate as an SCIF.
