Using External Reference for the DC2692
To use an external reference to drive the DC2692, move
the jumper named REF SEL (JP1) from the INT posi-
tion to the EXT position. Use the REF turret to drive the
reference voltage. If this is done after the DC2692 was
powered up, then the internal reference will need to be
disabled from the control register.
