2. If the extended accumulator contains the value 0C3H, register pair HL the value 12H, and
the carry flag = "0":
3. If 'ADC A,@HL' is followed by an 'ADS A,#im', the ADC skips on overflow to the instruction
a. 8 + 9 decimal addition (the contents of the address specified by the HL register is 9H):
b. 3 + 4 decimal addition (the contents of the address specified by the HL register is 4H):
Add and Skip on Overflow
immediately after the ADS. An 'ADS A,#im' instruction immediately after the 'ADC A,@HL'
does not skip even if overflow occurs. This function is useful for decimal adjustment
operations.
