C89C89D0D0

(S00 Option)

S(00-99): C(25-102) C(25-102) D(0-30)D(0-30) indicating threshold level and dynamic slope.

1st and 2nd C(25-102) indicates rising and falling threshold level from C25 to C102 that corresponds to ~20% to

~80% switch point threshold level with a step of ~0.78%.

1st and 2nd D(0-30) indicates rising and falling threshold dynamic slope from D1 to D30 that corresponds to

~0.225 to ~0.975%/mV with a step of ~0.025%/mV.
