Operation
Description
dst
The destination operand is adjusted to form two 4-bit BCD digits following a binary addi-
tion or subtraction operation on BCD encoded bytes. For addition (ADD and ADC) or
subtraction (SUB and SBC), Table 21 indicates the operation performed. If the destination
operand is not the result of a valid addition or subtraction of BCD digits, the operation is
undefined.
