DAU flags are affected by the ALU or ALU/ACS operation (except for the split-mode function which does not affect the flags). If there is no ALU or
ALU/ACS operation, the DAU flags are affected by the ADDER or BMU operation.
If
auc0
[10] (FSAT field) is set, the result of the add/subtract of the first two operands is saturated to 32 bits prior to adding/subtracting the third operand
and the final result is saturated to 32 bits.
§ If
auc0
[9] = 1, the least significant bit of
p1>>15
is cleared.
This split-mode instruction does not affect the DAU flags. Do not set FSAT for this instruction because if FSAT is set, the entire 32 bits are saturated.
