CalStart[15:0]
Metering calibration start command:
6886H: Power-on value. Metering function is disabled.
5678H: Metering calibration startup command. After 5678H is written to this register, registers 21H-2BH resume to their power-
on values. The 90E21/22/23/24 starts to meter and output energy pulses regardless of the correctness of diagnosis. The
CalErr[1:0] bits (SysStatus, 01H) are not set and the WarnOut/IRQ pins do not report any warning/interrupt.
8765H: Check the correctness of the 21H-2BH registers. If correct, normal metering. If not correct, metering function is disabled,
the CalErr[1:0] bits (SysStatus, 01H) are set and the WarnOut/IRQ pins report warning/interrupt.
Others: Metering function is disabled. The CalErr[1:0] bits (SysStatus, 01H) are set and the WarnOut/IRQ pins report warning/
interrupt.
Address: 21H
Type: Read/Write
Default Value: 0015H

PLconstH[15:0]
The PLconstH[15:0] and PLconstL[15:0] bits are high word and low word of PL_Constant respectively.
PL_Constant is a constant which is proportional to the sampling ratios of voltage and current, and inversely proportional to the
Meter Constant. PL_Constant is a threshold for energy calculated inside the chip, i.e., energy larger than PL_Constant will be
accumulated in the corresponding energy registers and then output on CFx.
It is suggested to set PL_constant as a multiple of 4 so as to double or redouble Meter Constant in low current state to save ver-
ification time. PLconstH takes effect after PLconstL are configured.
For details, please refer to IDT application note AN-641.
