the battery. Charging starts with default operational parameter
settings. It is possible to change settings using the controls on
the left side of the
Opr Control & Status
tab.
SETTING INTERRUPTS
The

microcontroller of a status change in the corresponding charger
function. All interrupts are disabled by default, and each interrupt
can be separately enabled by issuing an I

C write to Register 0x09.
The
Interrupts & Timers
tab (see Figure 3) in the GUI controls
the register settings. Register 0x0A is automatically read after
every 0.3 second timeout from the last user action involving the
GUI. When a certain interrupt is enabled, and there is a status
change in the corresponding function during charging, an
interrupt message is shown in the
Opr Control & Status
tab
(see Number 3 in Figure 2).
SETTING TIMERS
The default settings of the timers are shown in Figure 3. Changing
the timer settings can be done by clicking items in the
Timer
Settings (Write to Register 0x06)
box.
Register 0x09 controls the interrupt enables, and Register 0x06
controls the timer settings.
