Software
Figure 14. Register View
The
Show Revisions
button displays the current version of the GUI.
The
Write to RAM
button writes all currently selected options from all tabs to the bq76PL455A-Q1
registers in RAM. In most cases, the use of this button is superfluous, since most controls in the GUI are
active controls and settings are saved immediately upon selection.
The
Soft Reset
button causes the SOFT_RESET bit in the Device Control register (register 12) to be set
and initiates a reset of the digital control logic in the bq76PL455A-Q1. Please refer to the bq76PL455A-Q1
data sheet (
) for the full description of the implications of this action. This action is not normally
required or suggested, and results in the indication of
Sys Reset
and
System Faults
on the
Faults
tab
(since unexpected resets are considered faults). These faults show as soon as the next request for Polling
is made or the
Query All
button is clicked on the
Faults
tab.
NOTE:
Failure to clear the
Sys Reset
and
System Faults
after initiating a Soft Reset will prevent the
ability to enable the balancing function or the
Continue on Fault
check box on the
Balancing
tab is selected.

Register View Window
The
Register View
window contains nine buttons:
Read All
,
Read Selected Value
,
Write Selected Value
,
Write Selected Broadcast
,
Import
,
Export
,
Save all to EEPROM
,
Update Checksum
, and
Hide
.
The
Read All
button reads all registers of the bq76PL455A-Q1 on the currently selected bq76PL455EVM,
and updates the register values in the Register View window. The selected bq76PL455EVM address is
displayed on the window title bar of the Register View window (see
).
Verify a properly written value or read only the value of an individual register by clicking on any column for
a particular register and clicking the
Read Selected Value
button. The GUI reads the register from the
bq76PL455A-Q1 and updates the Value column for the selected register with the data read. When a
register is selected, a small pointer appears in the far left column next to the address of the selected
register.
