CHAPTER 4: INSTRUCTION SET
ADC %B,%A,n4 Add with carry A reg. to B reg. in specified radix 2 cycles
Function: B ← N's adjust (B + A + C)
Adds the content of the A register and carry (C) to the B register. The operation result is
adjusted with n4 as the radix. The C flag is set by a carry according to the radix.
Code:
Mnemonic MSB LSB
ADC %B,%A,n4 100001101 [10H-n4] 10D0H–10DFH
Flags: EICZ
↓ – ↕↕
Mode: Src: Register direct
Dst: Register direct
Extended addressing: Invalid
Note: n4 should be specified with a value from 1 to 16.
ADC %B,[%ir],n4 Add with carry location [ir reg.] to B reg. in specified radix 2 cycles
Function: B ← N's adjust (B + [ir] + C)
Adds the content of the data memory addressed by the ir register (X or Y) and carry (C) to the
B register. The operation result is adjusted with n4 as the radix. The C flag is set by a carry
according to the radix.
