ADC_INIT_ERROR[0]

Error occurred in ADC

initialization.

1. ADC SPI signal integrity

issue.

2. Error in ADCs.

1. Check signal integrity of

SPI connections between the

ADE9178 and ADCs.

2. See the Quick Start section

and ensure that ADC related

parameters are configured

properly.

3. Read STATUS registers of

ADCs to check if any error bits

are set.

4. Reset the ADE9178 and

ADCs. Initialize ADCs using

ADC_INIT of ADC_CONTROL

1. Read STATUS registers of

ADCs to check if any error bits

are set.

2. Reset the ADE9178 and

ADCs. Initialize ADCs using

ADC_INIT of ADC_CONTROL

ERROR0[1]

Internal Error Occurred.

Reset the ADE9178 and ADCs.

Initialize ADCs using ADC_INIT

of ADC_CONTROL register after

ADE9178 reset.

Reset the ADE9178 and ADCs.

Initialize ADCs using ADC_INIT

of ADC_CONTROL register after

ADE9178 reset.

ERROR1[2]

Internal Error Occurred.

Reset the ADE9178 and ADCs.

Initialize ADCs using ADC_INIT

of ADC_CONTROL register after

ADE9178 reset.

Reset the ADE9178 and ADCs.

Initialize ADCs using ADC_INIT

of ADC_CONTROL register after

ADE9178 reset.

ERROR2[3]

Internal Error Occurred.

Reset the ADE9178 and ADCs.

Initialize ADCs using ADC_INIT

of ADC_CONTROL register after

ADE9178 reset.

Reset the ADE9178 and ADCs.

Initialize ADCs using ADC_INIT

of ADC_CONTROL register after

ADE9178 reset.

ERROR3[4]

Internal Error Occurred.

Reset the ADE9178 and ADCs.

Initialize ADCs using ADC_INIT

of ADC_CONTROL register after

ADE9178 reset.

Reset the ADE9178 and ADCs.

Initialize ADCs using ADC_INIT

of ADC_CONTROL register after

ADE9178 reset.

ERROR4[5]

Internal Error Occurred.

Reset the ADE9178 and ADCs.

Initialize ADCs using ADC_INIT

of ADC_CONTROL register after

ADE9178 reset.

Reset the ADE9178 and ADCs.

Initialize ADCs using ADC_INIT

of ADC_CONTROL register after

ADE9178 reset.

ADC_CRC_ERROR[6]

ADC SPI CRC Error Occurs.

ADC SPI CRC errors are

detected on the samples read

from the ADCs.

1. Check signal integrity of

SPI connections between the

ADE9178 and ADCs.

2. Ensure that the ADC related

registers are configured correctly

as per the Quick Start section.

3. Read STATUS registers of

ADCs to check if any error bits

are set.

4. If error persists, reset

the ADE9178 and ADCs and

perform ADC initialization again.

If CRC error occurs, the

ADE9178 automatically discards

the ADC samples, and previous

good samples are used for

measurements.

ERROR5[7]

Internal Error Occurred.

Reset the ADE9178 and ADCs.

Initialize ADCs using ADC_INIT

of ADC_CONTROL register after

ADE9178 reset.

Reset the ADE9178 and ADCs.

Initialize ADCs using ADC_INIT

of ADC_CONTROL register after

ADE9178 reset.

DREADY_FREQ_ERROR[8]

ADC Data Ready Frequency

Error. This bit is set when ADC

Data Ready frequency is not 4

ADC DREADY frequency might

be configured wrong. ADCs

reset while ADC is running.

1. Check signal integrity of the

DREADY signal.

2. Reset the ADE9178 and

ADCs. Initialize ADCs using

Clear DREADY_FREQ_ERR bit

by writing 1 to bit 8 of ER-

ROR_STATUS register. If the bit

re-asserts reset the ADE9178
