Unipolar / bipolar reset of DAC with J1, J6, J11, J16

The DAC 2815BP has a clear input which allows setting the output voltage
at a defined output value after reset or after the watchdog time sequence.
You can jumper-select (via J1, J6, J11, J16) whether the unit is loaded with 0000Hex
(unipolar zero) or 0800Hex (bipolar zero).
Jx = "0" means jumper unplugged = unipolar zero and Jx = "1" = bipolar zero.
This selection alway sets 2 channels.
The following jumpers set the following channels:
a) If J1, J6, J11 and/or J16 are plugged ("0"), then the DAC registers are loaded with
value 0000Hex as soon as the clear input is activated.
A clear is generated by a system reset, at initialisation, or after the watchdog time (if
set) has run down.
The outputs are set to following output values after a reset in unipolar mode:
b) If J1, J6, J11, and/or J16 are unplugged ("1"), then the DAC registers are loaded
with value 0800Hex as soon as the clear input is activated.
A clear is generated by a system reset, at initialisation, or after the watchdog time (if
set) has run down.
