Bit Mnemonic Default Description
1 FREQSEL 0
Configuration bits to select period or frequency measurement for PER_FREQ register
(Address 0x0A).
FREQSEL Result
0 PER_FREQ register holds a period measurement.
1 PER_FREQ register holds a frequency measurement.
0 WAVEN 0 When this bit is set, waveform sampling mode is enabled.

Logic 1 enables I
rms
no load threshold detection. The level is defined by the setting of the
VANOLOAD bits.
[5:4] VANOLOAD 00 Apparent power no load threshold.
VANOLOAD Result
00 No load detection disabled
01 No load detection enabled with threshold = 0.030% of full scale
10 No load detection enabled with threshold = 0.015% of full scale
11 No load detection enabled with threshold = 0.0075% of full scale
