Description
Trim-out current sense amplifier offset (dc offset correction).
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.
Allow the microprocessor to write directly to CBD as a possible way of adding an additional
port. This might be a blinking led or a fail signal to the system.
Microprocessor clear of CBD latch (if configured as latching) folowing an SMBAlert.
Description
Trim-out offset due to external resistor divider tolerances (for common-mode correction).
Description
Unused.
External Divider Tolerance Trim Range (Common-Mode Trim Range).
