ALATCH
R/W
0h
When the Alert Latch Enable bit is set to Transparent mode, the
Alert pin and Flag bit reset to the idle state when the fault has been
cleared.
When the Alert Latch Enable bit is set to Latch mode, the Alert pin
and Alert Flag bit remain active following a fault until the DIAG_ALRT
Register has been read.
0h = Transparent
1h = Latched
14
CNVR
R/W
0h
Setting this bit high configures the Alert pin to be asserted when
the Conversion Ready Flag (bit 1) is asserted, indicating that a
conversion cycle has completed.
0h = Disable conversion ready flag on ALERT pin
1h = Enables conversion ready flag on ALERT pin
13
SLOWALERT
R/W
0h
When enabled, ALERT function is asserted on the completed
averaged value.
This gives the flexibility to delay the ALERT until after the averaged
value.
0h = ALERT comparison on non-averaged (ADC) value
1h = ALERT comparison on averaged value
12
APOL
R/W
0h
Alert Polarity bit sets the Alert pin polarity.
0h = Normal (Active-low, open-drain)
1h = Inverted (active-high, open-drain )
11
ENERGYOF
R
0h
This bit indicates the health of the ENERGY register.
If the 40 bit ENERGY register has overflowed this bit is set to 1.
0h = Normal
1h = Overflow
Clears when the ENERGY register is read.
