3.3 Software / Algorithm Requirements
3.3.1 Special Execution Requirements
The Current Measurement Arbitration function shall be executed every other motor control loop (125us).
3.3.2 Software Algorithm Decomoposition
The Current Measurement Arbitration function shall indicate the signal availability 1 is TRUE when all the
following conditions are satisfied

the duration less than a field configurable value,
MotCurrQlfr1 is NOT equal to Failed,
CurrMeasCorrlnSts of Phase A, B, C is TRUE or CurrMeasCorrlnSts bits for Phase A, B, C is equal to
CORRLNSTSCOMPCON1_ULS_U08.
The Current Measurement Arbitration function shall indicate the signal availability 2 is TRUE when all the
following conditions are satisfied
MotCurrRollgCntr2 is NOT equal to the previous value or MotCurrRollgCntr2 is equal to the previous value for
the duration less than a field configurable value,
MotCurrQlfr2 is NOT equal to Failed,
CurrMeasCorrlnSts of Phase D, E, F is TRUE or CurrMeasCorrlnSts bits for Phase D, E, F is equal to
CORRLNSTSCOMPCON2_ULS_U08.
The Current Measurement Arbitration function shall only use MotCtrlMotCurrCorrdA,
MotCtrlMotCurrCorrdB, MotCtrlMotCurrCorrdC in Q and D axes current calculation, if signal availability 1
is TRUE and signal availability 2 is FALSE.
The Current Measurement Arbitration function shall only use MotCtrlMotCurrCorrdD,
MotCtrlMotCurrCorrdE, MotCtrlMotCurrCorrdF in Q and D axes current calculation, if signal availability 2
