REGISTER OPERATION
Asynchronous operation. Reset the input and DAC register to a predetermined value. The DAC8820
is reset to all 0s.
Load the input register with all 16 data bits.
Load the DAC register with the contents of the input register.
The input and DAC register are transparent.
LDAC and WR are tied together and programmed as a pulse. The 16 data bits are loaded into the
input register on the falling edge of the pulse and then loaded into the DAC register on the rising
edge of the pulse.
No register operation.
