Startup Options Dialog
This dialog controls whether or not the WinGUI sets certain options and registers at startup. If a Group-3
register value is affected, it is done by the WinGUI writing the new value to the RAM register after the
POR period; the value is not written to the OTP-EPROM. OTP-EPROM is normally shipped blank from the
factory. Overwriting these RAM registers at startup prevents many FAULT and ALERT bits from triggering
at startup, and is done as a user convenience.
The option checkboxes are shown below in the state the WinGUI is shipped in. If the user changes any
checkbox states, the new defaults are saved automatically when the WinGUI exits.
BROADCAST MODE when checked, brings up the interface set to broadcast
messages to all devices, no data is shown. In broadcast mode, the WinGUI does
not know which device to read, so no register data is displayed.
If this box is not checked, the interface comes up ready to read/write device 1.
SET COV [
…
] sets the COV threshold to 5.0V, its highest value
DISABLE COV sets the CONFIG_COV[DISABLE] bit, disabling COV FAULTs
DISABLE CUV sets the CONFIG_CUV[DISABLE] bit, disabling CUV ALERTs
CLEAR LATCHED BITS clears all FAULT and ALERT bits latched in the FAULT and ALERT registers,
which may have otherwise normally been set by startup conditions, i.e. Power-On-Reset
ENABLE VBRICK sets the ADC_CONTROL[GPAI] and FUNC_CONFIG[GPAI_SRC] bits. This causes
the VBRICK value (BAT-VSS) to be measured on each conversion cycle.
READ ALL VOLTAGES sets the bits ADC_CTRL[CS2:0] to 101b to convert all VCn inputs at each
conversion request
READ ALL TEMPERATURES sets the bits ADC_CTRL[TS2:1) to convert both thermistor TSn) inputs at
each conversion cycle. It also sets the bits IO_CTRL[TS2:1] to turn on the thermistor power
DYNAMICALLY CONTROL ADC_ON sets the bits FUNC_CONFIG[ADCT1:0] to the value 01b,
changing the conversion timing from the default 3
µ
s to 6
µ
s. The 6
µ
s setting is recommended for best
accuracy. This checkbox also causes the GUI to set the ADC_CTRL[ADC_ON] bit before each
conversion, convert, then set the ADC_ON bit back to 0. This is done around each conversion request,
whether hardware or software
