ADC %B,[%ir]+,n4
ADC [%ir],%B,n4
Add with carry B reg. to location [ir reg.] in specified radix
2 cycles
Function:
[ir]
←
N's adjust ([ir] + B + C)
Adds the content of the B register and carry (C) to the data memory addressed by the ir
register (X or Y). The operation result is adjusted with n4 as the radix. The C flag is set by a
carry according to the radix.

Add with carry location [ir reg.] to B reg. in specified radix and increment ir reg. 2 cycles
Function:
B
←
N's adjust (B + [ir] + C), ir
←
ir + 1
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. Then increments the ir register
(X or Y). The flags change due to the operation result of the B register and the increment result
of the ir register does not affect the flags. The C flag is set by a carry according to the radix.
