(b) Detecting
When it is received an optical signal, a signal outputs from RXD terminal at the following timing.
It is outputted in the pulse width fixed at the time of SIR mode (9.6k to 115.2kbps).
It is outputted in the pulse width which is the same as the input signal at the time of MIR mode (0.576M, 1.152Mbps)
and FIR mode (4Mbps).
But, as for the pulse width of the input signal, it is based on IrDA Physical Layer Specification.
