Precan
Precanceller Disable. When held to Logic ’1’, the internal path from LOUT to the
precanceller is forced to VBias thus bypassing the precanceller section. When logic ’0’, the
LOUT to the precanceller path is enabled and functions normally. An internal pulldown (50
kΩ) is provided on this pin.
