Configuration Switching
15.1.2.2 BANKA = 0, BANKB = 1
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.
15.1.2.3 BANKA = 1, BANK B = 1
If strobe pin is 1, configuration is defined by BANKS. BANKS is toggled at each falling edge of the strobe
pin.
If strobe pin is 0, MC33596 configuration is OFF.
If a message is received during state A or state B, current state remains the same up to end of message.
If a read or write access is done using SPI, the next sequence will begin with state A whatever was the
active state before SPI access by MCU.
15.1.3 Strobe Oscillator Switch Control
The conditions to enter strobe oscillator switch control are:
By simply writing BANKA and BANKB, the active banks will be defined.
The MCU can override strobe oscillator control by controlling the strobe pin level. If MCU I/O port is in
high impedance, the strobe oscillator will control the OFF/ON state of the MC33596. The various
available sequences are described in the following subsections.
