Immediate DAC Update Mode

The processor unit sends the 16-bit word to be converted to the first register of the selected DAC. If that DAC channel has previously been jumpered to, it will automatically pass the contents of the first DAC register into the second register and update the analog output. There is one jumper that enables/disables all eight DAC channels to be in the IMMEDIATE UPDATE MODE as described above, or in the DELAYED UPDATE MODE. Jumper definition and locations are described in “Program Controlled and External Start Convert Mode” on page 2-9.
