Notes: (1) Set to 1 when there is a carry or borrow from bit 11; otherwise cleared to 0.
(2) If the result is zero, the previous value of the flag is retained; otherwise the flag is cleared to 0.
(3) Set to 1 if decimal adjustment produces a carry; otherwise retains value prior to arithmetic operation.
(4) The number of states required for execution is 4n + 9 (n = value of R4L). 4n + 8 for HD64F38024,
H8/38024S Group, and H8/38124 Group.
(5) Set to 1 if the divisor is negative; otherwise cleared to 0.
(6) Set to 1 if the divisor is zero; otherwise cleared to 0.
