15.13 Notes on Using the IrDA Module

15.13.1

Shortest Pulse Width in Reception

Pulses shorter than the lower limit (1.41 μs) are not recognized.
15.13.2

Asynchronous Basic Clock for Serial Communication Interface

The IrDA module receives the basic clock with a frequency which is 16 times as high as the communication bit rate from
the SCI and operates in combination with the clock. Although one-bit period of the SCI can be set to 16 or 8 clock cycles,
the IrDA module supports the SCI that one-bit period is set to 16 clock cycles.
