Data-Acquisition Interface
When any ADC cell conversion is completed,
the value is compared with OVTHRSET,
OVTHRCLR, UVTHRSET, and UVTHRCLR.
The difference between UVTHRSET and
UVTHRCLR or OVTHRSET and OVTHRCLR
is effectively a digital hysteresis for the alert
threshold. If:
CELL
The corresponding alert bits are set. The over-
voltage alert bit is cleared when:
CELL
The undervoltage alert bits are cleared when:
CELL
When a scan of conversions is completed, a
mismatch alert is generated if the result of:
MAXCELL - MINCELL > MSMTCH
Set MSMTCH = 0xFFFF to disable mismatch
alerts.
