DS2780 Standalone Fuel Gauge IC
CONTROL REGISTER
All CONTROL register bits are read and write accessible. The CONTROL register is recalled from Parameter
EEPROM memory at power-up. Register bit values can be modified in shadow RAM after power-up. Shadow RAM
values can be saved as the power up default values by using the Copy Data command.

PIO Sense and Control
Read values
0: PIO pin ≤ Vil
1: PIO pin ≥ Vih
Write values
0: Activates PIO pin open-drain output driver, forcing the PIO pin low
1: Disables the output driver, allowing the PIO pin to be pulled high or
used as an input
Power-up and SLEEP mode default: 1 (PIO pin is hi-Z)
Note: PIO pin has weak pulldown
EEPROM REGISTER
The EEPROM register provides access control of the EEPROM blocks. EEPROM blocks can be locked to prevent
alteration of data within the block. Locking a block disables write access to it. Once a block is locked, it cannot be
unlocked. Read access to EEPROM blocks is unaffected by the lock/unlock status.
