Table 19.1 shows the IrDA pin configuration.
Table 19.1 Pin Configuration
Note: Clock input from the serial clock pin cannot be set in IrDA mode.
19.3
The IrDA has the following internal registers. Refer to section 37, List of Registers, for more
details on the addresses and states of these registers in each operating mode.
• IrDA mode register (SCIMR)
19.3.1
SCIMR selects IrDA or SCIF mode and selects the IrDA output pulse width.
IrDA operates when the IRMOD bit is set to 1. When the IRMOD bit is cleared to 0, IrDA can
operate as an SCIF.
