This section describes how the MC33696 controller executes sequences of operations, relative to the
selected mode. The controller is a finite state machine, clocked at T
Figure 2
There are four different modes: configuration, transmit, receive, and standby/LVD. Each mode is exclusive
and can be entered in different ways, as follows.
After a Power-on Reset (POR), the circuit is in standby mode (see
contents are set to the reset value.
At any time, a low level applied to CONFB forces the finite state machine into configuration mode,
whatever the current state. This is not always shown in state diagrams, but must always be considered.
