The DSR register condition code bit (DC) is always updated on the basis of the result of an
unconditional ALU or shift operation instruction. Conditional instructions do not update the DC
bit. Multiply instructions, also, do not update the DC bit. DC bit updating is performed by means
of the CS[2:0] bits in the DSR register. The DC bit update rules are shown in table 3.19.
