Peripheral Simulation

For Analog Devices ADuC7026 — Digital/Analog Converter 1

Simulation support for this peripheral or feature is comprised of:

• Dialog boxes which display and allow you to change peripheral configuration.
• VTREGs (Virtual Target Registers) which support I/O with the peripheral.

These simulation capabilities are described below.

DAC 1 Dialog

The DAC 1 dialog displays and configures the Digital/Analog converter. The controls in this dialog are separated into several logical groups.

DAC Control Group

• DAC1CON (Control Register) displays and configures the D/A Converter control register.
• DACCLR (DAC Clear) is set to enable normal DAC operation. If reset, the data register of the DAC is set to zero.
• DACCLK (DAC Update Rate) is set to update the DAC using Timer 1. If reset, the core clock is used.
• DACBYP (Buffer Bypass) is set to bypass the output buffer. Resetting this bit buffers the DAC output.
• Range (DAC Range Setting) selects the voltage range.

DAC Data Group

• DAC1DAT (Data Register) contains the 12-bit digital data to be converted.

DAC Output Group

• DAC1 (Output Register) displays the converted analog voltage value.
