If the bit time exceeds t
Atmel CryptoAuthentication will enter
sleep mode and the Wake token must
be resent.
Atmel CryptoAuthentication will initiate
the first low going transition after this
time interval following the end of the
Transmit flag
After Atmel CryptoAuthentication
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
