4.2.2.1
ENABLE AUTO INT_EN
The “Enable Auto INT_EN” control is a GUI control convenience. Under normal
operation, for most of the integration parameter settings, changes do not take effect
until the PAC1921 is placed in the Read state. When the “Enable Auto INT_EN” control
is activated (light green – shown as “Enabled” in
), it automatically places the
PAC1921 into the Read state and back to Integrate state whenever a Main Configura-
tion control is changed. It also updates the GUI calculations. When the
“Enable Auto INT_EN” control is disabled (dark green), the user must place the device
in the Read state before the “I_RES”, “V_RES”, “SAMPLES”, “VSENSE FILT_EN” and
“VBUS FILT_EN” changes take effect, and to update the GUI calculations.
It is recommended that the “Enable Auto INT_EN” control be activated when using
the GUI.
