chip will transition to sleep.
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
