Section 14 Serial Communication Interface 3 (SCI3, IrDA)
14.6.1
During transmission, the output signals from the SCI3 (UART frames) are converted to IR frames
using the IrDA interface (see figure 14.16).
For serial data of level 0, a high-level pulse having a width of 3/16 of the bit rate (1-bit interval) is
output (initial setting). The high-level pulse can be selected using the IrCKS2 to IrCKS0 bits in
IrCR.
According to the standard, the high-level pulse width is defined to be 1.41 µs at minimum and
(3/16 + 2.5%) × bit rate or (3/16 × bit rate) +1.08 µs at maximum. For example, when the
frequency of system clock φ is 10 MHz, being equal to or greater than 1.41 µs, the high-level pulse
width at minimum can be specified as 1.6 µs.
For serial data of level 1, no pulses are output.
