CPL is the negative input of CMP1, controlled by cap, cntd, SCMPL1:0, CAPM, and CAPTG. Details are shown

in Chart 14.

When cap=0 and cntd=0, the output of CPL is irrelevant to CAPM and CAPTG. It is directly selected by

SCMPL1:0.

When cap=0 and cntd=1, it’s under short testing mode. The output of CPL is fixed to be Vcntd.

When cap=1, it’s under capacitor measuring mode. At this time, the output of CPL is irrelevant to cntd and

SCMPL1:0. When CAPM=0, it means low and medium capacity measuring. The output of CPL is controlled

by CAPTG; they are Vcapc1 and Vcapd1. When CAPM=1, it means high capacity measuring. The output of

CPL is controlled by CAPTG. They are Vcapc2 and Vcapd2.
