Pin
Whatever the SYS bits setting (indicating phases presence and configuration), bit BSF is
always calculated, but it is valid only in cases SYS is 0, 1, 2 and 3. In fact in this case all the
three phase voltage signals (u
In cases SYS is 4, 5, 6, 7, only two or one voltage signal are available (u
the sequence cannot be checked. Bit BSF is always set in the status byte, but it must be
ignored.
In standalone application for SYS = 0, 1 or 2 (3-phase systems) bit BSF is available as
output on SDATD pin.
Pin description versus SYS configuration (u
current signals)
Phase active powers do not have the same sign (status bit BIF)
The 3-phase status bit BIF is produced from status bit SIGN of each phase. If bit SIGN is not
equal in all three phases (R, S and T), then bit BIF is set.
In a standalone application for SYS = 0, 1 or 2 (3-phase system) bit BIF is available as
output on SDATD pin.
Example 9: status bit BIF
EMI is detected
EMI tamper detection is enabled by configuring bits ENH = 1 and APL [1] = 1 (APL [1] sets
standalone application mode).
The DAH signal is checked to verify that:

If these condition are not verified the EMI tamper is detected.
