STATUS REGISTER
The Status Register contains seven read-only status flags. Bit 7 of the register is read-only and always
returns logic 0. The format of the register is shown in Figure 14. The various flags are described in the
paragraphs below.

PIO
- State of the PIO pin. This flag mirrors the logic state of the PIO pin, regardless of whether PIO is
set up as an input or an output. The PIO flag is updated every time Page 1 of memory (the page
containing the Status Register) is accessed by the host system.
LOCK
- Page 0 Lock. This flag indicates whether Page 0 is locked so that it cannot be written
(LOCK=1) or unlocked for read/write access (LOCK=0). This bit is set and cleared by the execution of
the Lock Register and Unlock Register commands. The power-on default value for this bit is logic 1
(locked).
OT
- Overtemperature. This bit indicates the presence (OT=1) or absence (OT=0) of an overtemperature
protection condition.
OV
- Overvoltage. This bit indicates the presence (OV=1) or absence (OV=0) of an overvoltage
protection condition.
UV
- Undervoltage. This bit indicates the presence (UV=1) or absence (UV=0) of an undervoltage
protection condition.
OC
- Overcurrent. This bit indicates the presence (OC=1) or absence (OC=0) of an overcurrent
protection condition.
DTW
- Discharge Termination Warning. This status bit is set to logic 1 when the Integrated Current
Accumulator (ICA) value drops below the Discharge Termination Warning (DTW) threshold or cell
voltage drops below discharge warning threshold V
DW.
This bit is reset to logic 0 when the ICA is higher
than the DTW threshold and the voltage of the cell is above V
DW
