From SHIPMENT - DEEP SLEEP state, if NSHIP pin is higher than VNSHIP_TH for at least TWAKEUP_NSHIP.

–

After TSHIP2NORMAL, the VREG regulator has reached its NORMAL state specification. After

TI2C_READY an RDY pulse is generated to mark the transition to NORMAL. This allows the MCU to

fully operate in its normal state, respond to watchdog, serve interrupts, and so on. L9961 is capable of

decoding I2C commands and receives new configurations

–

MCU should still wait for TCP_STARTUP when out of reset, before trying to operate the pre-driver stage

Upon receival of wakeup condition, transitions to other states are masked until NORMAL state has been fully

reached. Once the device enters NORMAL state, the logic starts a TVREG_UV_BLK blanking time on the VREG

UV comparator in order to prevent erroneously flagging UV conditions that would bring L9961 back to STANDBY

state.
