Description
39-0
ENERGY
R
0h
Calculated energy output.
Output value is in Joules.Unsigned representation. Positive value.
Conversion factor: 3.84mJ/LSB.
7.1.8 Charge Result (CHARGE) Register (Address = Ah) [reset = 0h]
The CHARGE register is shown in Table 7-10.

Calculated charge output. Output value is in Coulombs.Two's
complement value.
Conversion factor: 75μC//LSB.
7.1.9 Diagnostic Flags and Alert (DIAG_ALRT) Register (Address = Bh) [reset = 0001h]
The DIAG_ALRT register is shown in Table 7-11.
Return to the Summary Table.

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 = Disables 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 by setting the RSTACC field in the Configuration register.
10
CHARGEOF
R
0h
This bit indicates the health of the CHARGE register.
If the 40-bit CHARGE register has overflowed this bit is set to 1.
0h = Normal
1h = Overflow
Clears by setting the RSTACC field in the Configuration register.
