WISMO_READY Indication
This signal indicates the ready status of the WISMO218 after powering on. Please note that there is an
initial positive pulse of less than 200ms during power ON. For details, please refer to the power ON
diagram in the
sub-section. Once the WISMO218 is properly powered ON, the
WISMO_READY pin will set to HIGH level to acknowledge the successful powering ON of the
WISMO218 before it is ready to operate.
On the other hand, the level will go LOW before powering off.
