Description
Sets polarity of OrFET gate control (F
G
pin): 0 = inverted (low = on); 1 = normal (low =
off).
Allow the microprocessor to directly control the share clamp. 0 = normal share clamp
operation, that is, not clamped; 1 = assert share clamp, that is, clamped. See Table 43.
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. See Table 43.
Microprocessor clear of CBD latch (if configured as latching) folowing an SMBAlert.
See Table 43.

Current Sense Offset Trim
R/W
Trim-out offset due to external resistor divider tolerances (for common-mode
correction). This register is normally written to during the user calibration.

Current Sense DC offset Trim
R/W
Trim-out current sense amplifier offset (dc offset correction). Increasing this results in
more offset for the current sense. This register is normally written to during the user
calibration. It is used with Reg06H.
