ADuC7060/ADuC7061
DAC PERIPHERALS
DAC
The ADuC706x incorporates a voltage output DAC on chip. In
normal mode, the DAC resolution is 12-bits. In interpolation,
the DAC resolution is 16 bits with 14 effective bits. The DAC
has a rail-to-rail voltage output buffer capable of driving
5 kΩ/100 pF.
The DAC has four selectable ranges.

Set to 1 to enable the DAC in 16-bit interpolation mode.
Description
Set to 1 to power down DAC output (DAC output is tristated).
Clear this bit to enable the DAC.
Set to 1 to place the DAC output buffer in low power mode. See the Normal DAC Mode and Op Amp Mode
sections for further details on electrical specifications.
Clear this bit to enable the DAC buffer.
Set to 1 to place the DAC output buffer in op amp mode.
Clear this bit to enable the DAC output buffer for normal DAC operation.
Set to 1 to bypass the output buffer and send the DAC output directly to the output pin.
Clear this bit to buffer the DAC output.
Cleared to 0 to update the DAC on the negative edge of HCLK.
Set to 1 to update the DAC on the negative edge of Timer1. This mode is ideally suited for waveform generation
where the next value in the waveform is written to DAC0DAT at regular intervals of Timer1.
Set to 1 for normal DAC operation.
Set to 0 to clear the DAC output and to set DAC0DAT to 0. Writing to this bit has an immediate effect on the DAC
output.
Set to 0 to enable the DAC in normal 12-bit mode.
Used with interpolation mode.
Set to 1 to configure the interpolation clock as UCLK/16.
Set to 0 to configure the interpolation clock as UCLK/32.

Op Amp Mode
As an option, the DAC can be disabled and its output buffer
used as an op amp.
MMR INTERFACE
The DAC is configurable through a control register and a data
register.
