[10] Transmitter Wake Up Time is measured from Vcc power ON to valid light output in response to a TxD_IrDA pulse.
[11] The Max Optical PW is defined as the maximum time which the IR LED will turn on, this, is to prevent the long Turn On time for the IR LED.

An in-band optical signal is a pulse/sequence where the peak wavelength, l
are compliant with the IrDA Serial Infrared Physical Layer Link Specification version 1.4.
For in-band signals 115.2 kbit/s where 9 mW/cm2 ≤ EI ≤ 500 mW/cm2.
For in-band signals 1.152 Mbit/s where 22 mW/cm2 ≤ EI ≤ 500 mW/cm2.
For in-band signals 4 Mbit/s where 22 mW/cm2 ≤ EI ≤ 500 mW/cm2.
Latency is defined as the time from the last TxD_IrDA light output pulse until the receiver has recovered full sensitivity.
Receiver Wake Up Time is measured from Vcc power ON to valid RxD_IrDA output.
