The input to Clock can be stopped (=0Hz) during reset period and power down state (DP0=1).
However, the input level is to be H or L, and input of intermediate level is prohibited.

The reset width is defined as the time from the moment VDD or IOVDD has risen to 90%.
/RST has to be settled at “L” level at the time VDD or IOVDD has risen to 30%.
