MC33591 Technical Data
MOTOROLA
STATE MACHINE WITH STROBE OSCILLATOR CONTROL
Figure 15 details the state machine when the strobe oscillator is enabled (SOE=1).
Figure 15: State machine
with strobe oscillator control
State 2:
The circuit is in Sleep mode, except for the Strobe oscillator and the Strobe counter.
State 3:
The circuit is waiting for a valid ID word. If ID or its complement is detected, the state machine advances to state
4. If not, it will go back into sleep mode (state 2) at the end of the Strobe period.
State 4:
ID or its complement has been detected, Data Manager is waiting for Header or its complement. Time-out
counter is running. This counter will count up to 66 ( 1) times the strobe oscillator period (T
Strobe
).
State 5:
If Header has been received, data and clock signals are output on the SPI port until End of Message indicates the
data sequence end. If the complement of Header has been received, output data are complemented too.
For all states:
At any time, a low level applied on RESETB during more than one Ts forces the state machine to state 1. When
