Section 15 Serial Communication Interface (SCI, IrDA)
In the specification, the high pulse width is fixed at a minimum of 1.41 µs, and a maximum of
(3/16 + 2.5%) × bit rate or (3/16 × bit rate) + 1.08 µs. When system clock φ is 20 MHz, 1.6 µs can
be set for a high pulse width with a minimum value of 1.41 µs.
When the serial data is 1, no pulse is output.
Reception: In reception, IR frame data is converted to a UART frame by the IrDA interface, and
input to the SCI.
When a high pulse is detected, 0 data is output, and if there is no pulse during a one-bit interval, 1
data is output. Note that a pulse shorter than the minimum pulse width of 1.41 µs will be identified
as a 0 signal.
High Pulse Width Selection: Table 15.12 shows possible settings for bits IrCKS2 to IrCKS0
(minimum pulse width), and operating frequencies of this LSI and bit rates, for making the pulse
width shorter than 3/16 times the bit rate in transmission.
