Intel mcs-48 manual Addc A,#data Add Carry and Immediate Data to Accumulator

INSTRUCTION SET

ADDC A,@Rr Add Carry and Data Memory Contents to Accumulator

101111 0 0 0r i

The content of the carry bit is added to accumulator location 0 and the carry bit c;:leared. Then the contents of the resident data memory location aqdressed by register Or' bits 0-5*are added to the accumulator. Carry is affected.
