COMMUNICATION VERIFICATION REGISTERS

The ADE9153A includes three register that allow SPI operation

verification. The LAST_CMD (Address 0x4AE), LAST_DATA_16

(Address 0x4AC), and LAST_DATA_32 (Address 0x423) registers

record the received CMD_HDR and the last read or transmitted

data.

CRC OF CONFIGURATION REGISTERS

The configuration register CRC feature in the ADE9153A monitors

certain user and private register values. The results are stored in

the CRC_RSLT register. When enabled, the ADE9153A generates

an interrupt on IRQ if any of the monitored registers change the

value of the CRC_RSLT register.

CONFIGURATION LOCK

The configuration lock feature prevents changes to the ADE9153A

configuration. To enable this feature, write 0x3C64 to the

WR_LOCK register. To disable the feature, write 0x4AD1.

To determine whether this feature is active, read the

WR_LOCK register, which reads as 1 if the protection is

enabled and 0 if it is disabled.

When this feature is enabled, it prevents writing to addresses

from Address 0x000 to Address 0x073 and Address 0x400 to

Address 0x4FE.
