(tmp) ← (op2) || (op1)
(ACC) ← min((ACC),(tmp))
Description
Compares a signed 40-bit operand against the 40-bit ACC register contents. The 40-bit
operand is a sign-extended result of the concatenation of the two source operands op1
(LSW) and op2 (MSW). If the contents of the ACC register are greater than the 40-bit
operand, then the ACC register is loaded with it. Otherwise, the ACC register remains
unchanged. The MS bit of the MCW register does not affect the result.
