Escaped Mode Addressing
dst
This instruction subtracts the source operand from the destination operand. The destina-
tion operand stores the result. The source operand contents are unaffected. The eZ8 CPU
performs subtraction by adding the two’s complement of the source operand to the desti-
nation operand.
Using Escaped Mode Addressing, address modes R or IR specify a Working Register. If
the high nibble of the source or destination address is
inferred. For example, if Working Register R12 (
