Assembler Syntax
If Dg < Dh, then Dg
→ Dh
MIN Dg,Dh
MIN Dg,Dh
Writes the smaller of two signed values in a data register pair (Dg and Dh) to the second of the two
registers (Dh). If the first register is less than the second, the value of the first register is written to the
second. Otherwise, the second register is unchanged.
