ADC [%ir],%r

Function: [ir] [ir] + r + C
Adds the content of the r register (A or B) and carry (C) to the data memory addressed by the ir
register (X or Y).

ADC [%ir]+,%r
Function: [ir] [ir] + r + C, ir
Adds the content of the r register (A or B) and carry (C) to the data memory addressed by the ir
register (X or Y). Then increments the ir register (X or Y). The flags change due to the operation
result of the data memory and the increment result of the ir register does not affect the flags.
