duration.
the chip will transition to sleep.
If the bit time exceeds t
AT88SA102S will enter sleep mode and
the Wake token must be resent.
Atmel AT88SA102S will initiate the first low
going transition after this time interval
following the end of the Transmit flag
After Atmel AT88SA102S transmits the last
bit of a block, system must wait this interval
before sending the first bit of a flag
Pulses shorter than this in width will be
ignored by the chip, regardless of its state

Pulses shorter than this in width will be
