A/D Converter
The C868 includes a high performance / high speed 8-bit A/D-Converter (ADC) with 5
analog input channels. It operates with a successive approximation technique and uses
self calibration mechanisms for reduction and compensation of offset and linearity errors.
The A/D converter provides the following features:
– 5 multiplexed input channels, which can also be used as digital inputs
– 8-bit resolution with TUE of +/- 2 LSB8.
– Single or continuous conversion mode
– Interrupt request generation after each conversion
– Using successive approximation conversion technique via a capacitor array
– Built-in calibration of offset and linearity errors
– Powerdown in normal, idle and slow-down modes
The ADC supports two conversion modes - single and continuous conversions. For
each mode, there are two ways in which conversion can be started - by software.
Writing a ’1’ to bit field ADST starts conversion on the channel that is specified by ADCH.
In single conversion mode, bit field ADM is cleared to ’0’. This is the default mode
selected after hardware reset. When a conversion is started, the channel specified is
sampled. The busy flag ADBSY is set and ADST is cleared. When the conversion is
completed, an interrupt request signal is asserted and the 8-bit result is transferred to the
result register ADDATH.
In continuous conversion mode, bit field ADM is set to ’1’. In this mode, the ADC
repeatedly converts the channel specified by ADCH. Bit ADST is cleared at the
beginning of the first conversion. The busy flag ADBSY is asserted until the last
conversion is completed. At the end of each conversion, the interrupt request signal will
be asserted. To stop conversion, ADM has to be reset by software. If the channel number
ADCH is changed while continuous conversion is in progress, the new channel specified
will be sampled in the conversions that follow.
A new request to start conversion will be allowed only after the completion of any
conversion that is in progress.
