Conversion Modes
The ADC provides two sampling/conversion methods
—
software mode and
hardware mode. This section presents the user configuration options.

3.7.1
Software Mode
Software mode is selected by setting the CR0 bit 7 of the ADC to 1. Control
of conversions is managed by the RD and WR signals.
In this mode, the system can operate either in stand-alone or in loopback
mode. The stand-alone mode is the shipping configuration; this allows you to
immediately begin evaluation.
3.7.1.1
Stand-Alone Mode
A pulse initiates stand-alone mode. You supply the pulse by momentarily
pressing SW1. The ADC handles subsequent conversions automatically.

Loopback Mode
Loopback mode permits the ADC and DAC to operate synchronously. The
jumper conditions are shown in the following table.
