Chapter 6 XGATE (S12XGATEV2)
ADC
Operation
RS1 + RS2 + C
Adds the content of register RS1, the content of register RS2 and the value of the Carry bit using binary
addition and stores the result in the destination register RD. The Zero Flag is also carried forward from the
previous operation allowing 32 and more bit additions.

Set if bit 15 of the result is set; cleared otherwise.
Set if the result is $0000 and Z was set before this operation; cleared otherwise.
Set if a two´s complement overflow resulted from the operation; cleared otherwise.
