27 / 96 page  # $%&'!()% ADS dst,src Operation: Operand Operation Summary Bytes Cycles A, #im Add 4-bit immediate data to A and skip on overflow 1 1 + S EA, #imm Add 8-bit immediate data to EA and skip on overflow 2 2 + S A,@HL Add indirect data memory to A and skip on overflow 1 1 + S EA,RR Add register pair (RR) contents to EA and skip on overflow 2 2 + S RRb, EA Add EA to register pair (RRb) and skip on overflow 2 2 + S Description: The source operand is added to the destination operand and the sum is stored in the destination. The contents of the source are unaffected. If there is an overflow from the most significant bit of the result, the skip signal is generated and a skip is executed, but the carry flag value is unaffected. If 'ADS A,#im' follows an 'ADC A,@HL' instruction in a program, ADC skips the ADS instruction if an overflow occurs. If there is no overflow, the ADS instruction is executed normally. This skip condition is valid only for 'ADC A,@HL' instructions, however. If an overflow occurs following an ADS instruction, the next instruction is not skipped. Operand Binary Code Operation Notation A, #im 1 0 1 0 d3 d2 d1 d0 A ← A + im; skip on overflow EA,#imm 1 1 0 0 1 0 0 1 EA ← EA + imm; skip on overflow d7 d6 d5 d4 d3 d2 d1 d0 A,@HL 0 0 1 1 1 1 1 1 A ← A + (HL); skip on overflow EA,RR 1 1 0 1 1 1 0 0 EA ← EA + RR; skip on overflow 1 0 0 1 1 r2 r1 0 RRb,EA 1 1 0 1 1 1 0 0 RRb ← RRb + EA; skip on overflow 1 0 0 1 0 r2 r1 0 Examples: 1. The extended accumulator contains the value 0C3H, register pair HL the value 0AAH, and the carry flag = "0": ADS EA,HL ; EA ← 0C3H + 0AAH = 6DH ; ADS skips on overflow, but carry flag value is not ; affected. JPS XXX ; This instruction is skipped since ADS had an overflow. JPS YYY ; Jump to YYY. |
