●Two times slope
1. Setting V1[7:0], V2[7:0], step1[2:0] and step2[4:0] (cntck[2:0] = 0x0)
Datasheet
① = 50 µs × V1[7:0] / step1[2:0]
② = 50 µs × ( V2[7:0] - V1[7:0] ) / step2[4:0]
③ = 50 µs (The first step output the keeping voltage.)
④ = 50 µs × (( V2[7:0] - V1[7:0] ) / step2[4:0] – 1)
⑤ = 50 µs × V1[7:0] / step1[2:0]
2. Setting V1[7:0], V2[7:0] and step2[4:0] (step1[2:0] = 0x0 and cntck[2:0] = 0x0)
