Reception: During reception, IR frames are converted to UART frames using the IrDA interface
before inputting to SCI_1.
Data of level 0 is output each time a high-level pulse is detected and data of level 1 is output when
no pulse is detected in a bit cycle. If a pulse has a high-level width of less than 1.41 µs, the
minimum width allowed, the pulse is recognized as level 0.
High-Level Pulse Width Selection: Table 14.13 shows possible settings for bits IrCKS2 to
IrCKS0 (minimum pulse width), and this LSI's operating frequencies and bit rates, for making the
pulse width shorter than 3/16 times the bit rate in transmission.
