according to PHASORREPORT instance 1 (because of higher priority) and therefore
PHASORREPORT instance 2 will receive data which does not match its performance class and
report rate.

Rule 3:
This rule is only related to the connection of 3PHSUM block to the PHASORREPORT block. If
3PHSUM block is configured to use external DFT reference (from SMAI reference block), it shall
only be connected to the same PHASORREPORT block instance as the one the SMAI reference
block is connected to. In other words, both the SMAI reference block and 3PHSUM block (3PHSUM
block with external DFT reference) shall be connected to the same instance of PHASORREPORT
block (PHASOR1-32 of Instance number 1 or 2).

where SMAI3 is configured as the reference block for DFT reference external out (DFTRefExtOut)
and 3PHSUM uses external DFT reference (from SMAI3). Figures
