STATE MACHINES
Freescale Semiconductor, Inc.
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
the transition condition from one state to the next one is fulfilled, the transition time is one Ts (except for reaching
state 2). The transition time to state 2 is 2 ´ Ts (+ duration of the dummy byte if it is shifted out, only for transition
coming from state 5).
