(6) Using IrDA 115.2 Kbps with USB
115.2 Kbps without using the (16 − K)/16 division function.
When the system uses USB , set f
Therefore, only in this case, the following conditions can be used.

Clock for baud rate generator = φT0
Divided value for baud rate generator = 2 + (16 − 9)/16
Pulse width = 3/16
Baud rate = 36 MHz/128/(2 + 7/16) = 115.38 Kbps
This baud rate includes a +0.156 % error, but IrDA specification is within
±0.87 %.
Pulse width = (1/281.25 Kbps) × (2 × (1/16) + 3 × (2/16)) = 1.777 μs
This pulse width is greater than 1.41 μs (IrDA specification).
