Where PU = Power up bit; W = Diagnostic bits for current output broken or load resistance high (Not used on voltage
outputs.); OE = Output enable bits (bit 00 corresponds to output 0, bit 01 corresponds to output 1. ATTENTION: These bits
must be set to 1. C = Configure select bit; F = Full range bit; S = Sign bit (in 2’s complement)
