CONFIGURATION REGISTER
The Configuration Register contains six read/write configuration bits. Bits 3 and 2 are read only and
always return logic 1 when read. The format of the register is shown in Figure 15. The various bits are
described in the paragraphs below.

ACC
- Accumulator enable. Setting this bit to a logic 0 disables the ICA, CCA and DCA functions,
freeing up bytes 0, 2, 3, 4 and 5 in Page 2 for general purpose use. A logic 1 (power-on reset default) in
this bit enables the accumulators.
TH1, TH2
- Accumulator threshold bits. When the current accumulators are active, TH1 and TH2 select
one of four accumulator threshold values. See Table 5 for possible threshold values.
POR
- Power-on reset. A logic 0 in this bit indicates that a power-on reset has occurred. Writing a logic
1 resets this flag so that subsequent power-on reset events can be detected.
W
R/
host system to read from the PIO pin using the Access Channel command. A logic 0 in this bit configures
the device to allow the host system to write to the PIO pin using the Access Channel command. The
power-on reset default value of this bit is logic 1 (read).
- PIO pin read/write direction bit. Setting this bit to a logic 1 configures the DS2441 to allow the
AVG
- Voltage A/D sampling method. This bit controls whether the average value (logic 1) or the
minimum value (logic 0) of each 32-sample group is stored in the Voltage Register. The power-on reset
default value is logic 1 (average).
THE MANUFACTURING ID
The value stored in this 16-bit read-only register can be laser-programmed by Dallas Semiconductor to
provide pack customization. Fields in this register can encode information such as the pack
manufacturer, assembly location and capacity. Unless a custom value is requested, the DS2441 ships
with 0000h in this register. Contact the factory to request a custom Manufacturing ID value.
