10.3.5.1 BANKA = X, BANKB = 0
Register Access through SPI
State A
OFF
State A
OFF
State A
If strobe pin is 1, configuration is defined by Bank A, BANKS = 1.
If strobe pin is 0, MC33596 configuration is OFF.
If a message is received during State A, current state remains State A up to end of message.
10.3.5.2 BANKA = 0, BANKB = 1
State B
OFF
State B
OFF
State B
If strobe pin is 1, configuration is defined by Bank B, BANKS = 0.
If strobe pin is 0, MC33596 configuration is OFF.
If a message is received during State B, current state remains State B up to end of message.
10.3.5.3 BANKA = 1, BANK B = 1

Banks Bit
BANKS toggles at the end of each state A or state B.
If strobe is forced to 1, configuration is frozen according to BANKS value.
If a read or write access is done using SPI, the next sequence will begin with state A in whatever was the
active state before SPI access by MCU.

For all available sequences:
• State A and State B are defined by Bank A and Bank B.
• State A duration, TonA is defined by Bank A RON[3–0].
• State B duration, TonB is defined by Bank B RON[3–0].
• OFF duration, TonB is defined by Bank A ROFF[2–0].
• If strobe pin is 1, the state is ON and defined by BANKS at that time and remains this state up to
the release of strobe and end of message if a message is being received.
• If a message is being received during State A or B, current state remains State A or B up to end of
message.
