Most significant 24 bits of VATHR[47:0] threshold
used in phase apparent power data path.
Less significant 24 bits of VATHR[47:0] threshold
used in phase apparent power data path.
Most significant 24 bits of WTHR[47:0] threshold
used in phase total active power data path.
Less significant 24 bits of WTHR[47:0] threshold
used in phase total active power data path.
This memory location should be kept at 0x000000
for proper operation
No-load threshold in the apparent power data path
No-load threshold in the total active power data
path
This register must be set at 0x800000 to ensure the
correct functionality of no-load detection circuit
based on total active power (See No-load detection
based on total active power section for details).
This memory location should not be written for
proper operation
Register used in the digital integrator algorithm. If
the integrator is turned on, it must be set at
0xFF8000
Disables/enables the HPF in the current data path.
