[Description example]
DBNZ
• One is subtracted from the destination operand (dst) contents specified by the 1st operand and the
• If the subtraction result is not 0, data is branched to the address indicated with the 2nd operand ($addr16).
• The flag remains unchanged.
DBNZ B, $1215H; The B register contents are decremented. If the result is not 0, data is branched to 1215H
subtraction result is stored in the destination operand (dst).
When the subtraction result is 0, no processing is carried out and the subsequent instruction is executed.
