90E36A POLY-PHASE HIGH-PERFORMANCE WIDE-SPAN ENERGY METERING IC
Register 49 April 2, 2013
PMConfig
Measure Configuration in Partial Measurement mode
PMAvgSamples
Number of 8K Samples to be Averaged
PMIrmsLSB
LSB bits of PMRrms[A/B/C]
Address: 1BH
Type: Read/Write
Default Value: 0000H
Bit Name Description
15 - Reserved.
14 ReMeasure This bit is ‘1’-write-only. Write ‘1’ to this bit will trigger another measurement cycle.
13 MeasureStartZX
This bit configures start of measurement whether starts from zero crossing point.
0: Measurement start immediately (default)
1: Measurement start from zero-crossing point
12 MeasureType
This bit indicates the measurement type.
0: RMS measurement (default)
1: Mean Value (DC Average) measurement
11-1 - Reserved.
0PMBusy
This bit indicates the measure status. This bit is read-only.
0: Measurement done (default)
1: Measurement in progress
Address: 1CH
Type: Read
Default Value: 00A0H
Bit Name Description
15:0 - Number of 8K samples to be averaged in RMS/mean computation.
Address: 1DH
Type: Read
Default Value: 0000H
Bit Name Description
15:12 - Reserved.
11:8 IrmsCLSB
These bits indicate LSB of the corresponding phase RMS measurement result if the MeasureType bit (b12, PMConfig) =0.
These bits indicate MSB of the corresponding phase mean measurement result if the MeasureType bit (b12, PMConfig) =1.
7:4 IrmsBLSB
3:0 IrmsALSB
