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 17 for the contents of the input shift
register during the internal reference set-up command.
