INTERNAL REFERENCE SETUP

The on-chip reference is off at power-up by default. This

reference can be turned on or off by setting a software

programmable bit, DB0, in the control register. Table 16 shows

how the state of the bit corresponds to the mode of operation.

Command 111 is reserved for setting up the internal reference

(see Table 8). See Table 16 for the contents of the input shift
