Section 15 Serial Communication Interface (SCI and IrDA)
High-Level Pulse Width Selection: Table 15.10 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.
