DVP-ES2/EX2/SS2/SA2/SX2/SE Operation Manual - Programming
‣ There are 6 software zone comparators available exclusively for zone compare operation,
hence the limit of 6 comparisons for zone compare does not include the comparisons of
DHSCS and DHSCR.
‣ SS2/SA2/SE does not support software counter C232.

‣ The two groups can only be used once for each group, occupying 2 comparators. For
example, when DHSZ instruction uses A3 and A4 of group A comparators, only the other
2 comparators (A1, A2) are available for DHSCS and DHSCR instructions.
‣ When DHSCS uses I030 or I040, comparators A3 and A4 are no longer available for
