INPUT RANGEG0G1UNI/BIPRANGE

A write to this register sets the analog input range for all 8/16 analog inputs. For the

PC104-DAS16Jr/12, range is programmable; the lower four bits set the analog input

range. For the PC104-DAS16Jr/16, the lower two bits set the range; the Uni/Bip bit is

set by hardware and the Range bit is not used. The upper four bits are not used for

either board. The current range is determined by reading this register.
