L9963T FSM

The following picture shows all L9963T possible states.

Figure 12. L9963T FSM

Different state transition sequences occur according to the following different scenarios:

•

First power up: Reset state → Stand-by state → Regulators enabling state → Trimming & Config

Latch → Normal state (see Figure 13). The first power up sequence lasts TFIRST_POWERUP.

•

Wake up: Stand-by state → Regulators enabling state → Normal state. See Figure 14 for an example of

the wake up sequence triggered by a frame received on the vertical interface. In case of wake up triggered

by DIS release, the state transition is the same. The wake up sequence lasts TWAKEUP.

•

Go To Sleep: Normal state → Regulators disabling state → Stand-by state. The go to sleep sequence

lasts TGO2SLP.
