ERROR_STATUS Bit

Solution

0x1

Read/Write ADE9178 Register

N/A1

For more details on the

Summary: ADE9178 section.

Use macros in ade9178.h for

address.

0x2

Invalid device.

Read/Write ADE9178/ADC Register

N/A1

Verify that the device field is

correct.

0x3

Write to more than one

supported.

Write ADE9178 Register

N/A1

Make NUM_REGISTERS = 1

for write command.

0x4

applicable only when device

field is ADE9178. Read only

check is not done for ADC

devices.

Write ADE9178 Register

N/A1

For more details on the

registers read/write access,

see the Register Summary:

ADE9178 section.

0x5

Provided BAUD_RATE field

of WFS_CONFIG register is

not sufficient to stream all

channels that are enabled in

WFS_CONFIG.

Write ADE9178 Register

N/A1

Update BAUD_RATE. For

more details on minimum

baud rate, see the Waveform

Streaming section.

0x6

Configuration Lock is

enabled.

Write ADE9178 Register

N/A1

Unlock configuration registers

by writing 0 to CONFIG_LOCK

0x7

Slots configured in the

ADC_REDIRECTx register is

not supported.

ADC_REDIRECTx

ADC Datapath Redirection

N/A1

Verify that the value written to

the register is correct.

0x8

Command failed to execute.

ADC_CONTROL = 0x2

Initialize ADC

ADC_INIT_ERROR

Retry the command.

Read/Write ADC Register

N/A1

If ADE9178 is reset

while ADC_RUN = 1,

then subsequent ADC read/

writes may return the

COMMAND_FAILED code

even though the ADC read/

write is successful. It is

recommended to reinitialize

the ADCs after ADE9178

reset.

Number of ADCs configured

is incorrect.

ADC_CONFIG

Configure number of ADCs

N/A1

Check if the number of ADCs

being configured is between 1

and 4.

0x9

ADCs are not initialized.

ADC_CONTROL = 0x1

Start ADC data capture

N/A1

Verify that ADC initialization

is done by writing 2 to

ADC_CONTROL.

ADC_CONTROL = 0x5

Synchronize ADC

N/A1

Verify that ADC initialization

is done by writing 2 to

ADC_CONTROL.

0xA

Issue in SPI communication

between Host MCU and

ADE9178.

Read/Write ADE9178 Register

N/A1

Check CRC header values.

Reset ADE9178 if error

persists.

0xB

Synchronization already in

progress and has not yet

complete.

ADC_CONTROL = 0x5

Synchronize ADCs

N/A1

Synchronization is already

issued. Wait for it to complete.

Read/Write ADC Register

N/A1

Synchronization is already

issued. Wait for it to complete.
