90E36
POLY-PHASE HIGH-PERFORMANCE WIDE-SPAN ENERGY METERING IC
Function Description

August 24, 2011
3.7.4
PARTIAL MEASUREMENT MODE (M MODE)
In this mode, Voltage ADCs, Neutral Line ADC and digital circuits are
inactive.
The 90E36 measures the current RMS of one line cycle.
When the measurement is done, the 90E36 asserts the IRQ0 pin
high until the Partial Measurement mode exits.
In this mode, the user needs to program the related registers (includ-
ing PGA gain, channel gain, offset, etc.) to make the current RMS mea-
surement accurate. Refer to 5.2 Partial Measurement mode Calibration.
Please note that not all registers in this mode is accessible. Only the
Partial Measurement related registers (14H~1DH) and some special
registers (00H, 01H, 03H, 07H,0EH, 0FH) can be accessed.
