V_BCKP and VCC directly connected to a battery. To get L96 be on Perpetual Backup Mode I set FORCE_ON to low level and then send $PMTK 224 (Perpetual Backup Mode).
Should I hold FORCE_ON always pullup to VCC to stay L96 on full on mode all time or I can use a positive impulse (low → VCC → low) ?
The docs say only about keeping FORCE_ON float or low level BEFORE backup mode, but nothing say in what state FORCE_ON should be during full on mode.
UPD: I have tested with positive FORCE_ON impulse to wake up L96 from Perpetual Backup Mode. Result: 600 mc is a minimal hold time for FORCE_ON on VCC to get L96 be woken up.
Is it documented feature?
Please, answer me.
