Detailed Description

The DATA RAM data character specified by the last SRC instruction, plus the carry bit, are added to the accumulator. The carry bit will be set if the result generates a carry, otherwise. the data character is not affected.

The opcode for this instruction does not contain any additional data:

/ Example
        FIM   0P    0
        SRC   0P
        ADM

The adm operation above is carried out as follows:

   Accumulator   =   1 0 1 0
Data Character   =   0 1 1 1
Carry            =         0
                     -------
   Result      1     0 0 0 1
