Description (revision A)
In revision A silicon, the oscillator stops running in Stand-by (power-down) mode.
Correction (revision B)
When Stand-by mode is requested, the oscillator remains powered up. Also, critical registers (e.g.
calibration registers) maintain their values after power-up.
Description (revision A)
In revision A silicon, default values in the Temperature Gain and Temperature Offset registers need to be
adjusted after reset in order to achieve a zero-degree offset.
Correction (revision B)
Default values adjusted to:
Temperature Gain = 0x34E2E7
Temperature Offset = 0xF3E7D0
After reset, zero-degree offset is within ±5° C.
Description (revision A)
When using the E1, E2 pulse output in Normal format, with power factor less than one, pulses appear on
pulse output E2 (which is an indication of negative power). To determine the active energy pulse count use
the equation:
Active Energy Pulse Count = E1 – (2 × E2)
Correction (revision B)
In Normal format the E1 and E2 pulse frequencies are calculated from the Active Power register. Therefore
when:
1) Active energy is positive: Active Energy Pulse Count = pulse count on E1
2) Active energy is negative: Active Energy Pulse Count = pulse count on E2
