Register Description
The change of duration of one state (due to the STROBE pin level or a message being received) has no
influence on the timing of the following states (A, B, or OFF).
18
This section discusses the internal registers, which are composed of two classes of bits.
All registers can be accessed by the SPI. These registers are described below.
At power-on, the POR resets all registers to a known value (in the shaded rows in the following tables).
This defines the MC33696’s default configuration.
18.1 Configuration Registers (Description Bank A only)
Figure 25
RESET is a global reset. The bit is cleared internally, after use.
SL (Switch Level) selects the active level of the SWITCH output pin.

Access
If strobe pin is 0 the state is OFF.
If strobe pin is released from 0 while state is OFF, the initial OFF period is completed.
Configuration and command bits allow the MC33696 to operate in a suitable configuration.
Status bits report the current state of the system.
0 = no action
1 = reset all registers and counters
