time the circuit goes to the sleep−mode. In case of a wake up
request (from BUS or WAKE Pin) during this transition
time, the wake−up request has higher priority than
go−to−sleep and INH will not be deactivated.
Behavior in Case of Missing Supplies

provide fail safe functionality. In this way, a low-power mode

value, the transmitter output stages are disabled and flagged
on the ERR pin. Because the transmitter is responsible for
the major part of the power dissipation, this will result in
reduced power dissipation and hence a lower chip
temperature. All other parts of the IC will remain operating.
