 Test Circuit
In Figure 4, the following statuses are the initial statuses 1 to 4.
Initial status 1: Set V1 = V2 = V3 = V4 = V5 = 2.8 V, SW_CO = SW_CAO = SW_RSTO = SW_CLKO = OFF, V8 = 0 V, V9 = 5 V,
V12 = V13 = 0 V.
Initial status 2: Set V1 = V2 = V3 = V4 = V5 = 3.5 V in initial status 1.
Initial status 3: Set V9 = 0 V in initial status 2, and output 8 clocks^*1 from V8.
Initial status 4: Set V1 = V2 = V3 = V4 = V5 = 2.8 V, V8 = 0 V, V9 = 0 V, V12 = V13 = 0 V.
*1. 1 clock is defined as follows.
"H": Output of 5 V for 50 ms or more
"L": Output of 0 V for 50 ms or more
