Description
Sets polarity of PEN output. Refer to the Configuration table (Table 45).
Sets polarity of CBD output. Refer to the Configuration table (Table 45).
Sets polarity of DC_OK output. Refer to the Configuration table (Table 45).
Sets polarity of AC_OK output. Refer to the Configuration table (Table 45).
Sets polarity of OrFET gate control: 0 = inverted (low = on).
Allow the microprocessor to directly control the share clamp 0 = normal share clamp
operation, i.e., not clamped 1 = assert share clamp, i.e., clamped.
