REGISTER RESET STATE
The SHDN pin will reset all logic registers when taken high,
but only if DCIN is present as determined by DCDIV > VAC
+ VACH and DCIN above UVLO. Micropower shutdown
state will not be entered, but the LTC4110 will be idle and
not able to enter charge or calibration modes. If SHDN is
switched low then normal operation will resume.
While in register reset state, charge and calibration modes
are inhibited, and all registers including the backup fault bit
register are set to their default states and the internal timer
is reset. The status pin ACPb is active, but GPIO1, GPIO2
and GPIO3 are reset to their default states. The SMBus is
enabled, however, it is not able to communicate with the
LTC4110. The DCIN to DCOUT PowerPath controller is
functional and the VDD and VREF pin voltages remain.
MICROPOWER SHUTDOWN STATE
If the SHDN pin remains high when DCIN is removed as
detected by the undervoltage lockout UVLO (see VUVD),
micropower shutdown is entered, battery backup mode is
inhibited and all registers are reset. During this condition,
the level of the SHDN pin is ignored and has no effect.
