A/D Converters
For analog signal measurement, up to two 10-bit A/D converters (ADC0, ADC1) with
11 + 5 multiplexed input channels and a sample and hold circuit have been integrated
on-chip. 4 inputs can be converted by both A/D converters. Conversions use the
successive approximation method. The sample time (to charge the capacitors) and the
conversion time are programmable so that they can be adjusted to the external circuit.
The A/D converters can also operate in 8-bit conversion mode, further reducing the
conversion time.
Several independent conversion result registers, selectable interrupt requests, and
highly flexible conversion sequences provide a high degree of programmability to meet
the application requirements. Both modules can be synchronized to allow parallel
sampling of two input channels.
For applications that require more analog input channels, external analog multiplexers
can be controlled automatically. For applications that require fewer analog input
channels, the remaining channel inputs can be used as digital input port pins.
The A/D converters of the XC226xN support two types of request sources which can be
triggered by several internal and external events.
Parallel requests are activated at the same time and then executed in a predefined
sequence.
Queued requests are executed in a user-defined sequence.
In addition, the conversion of a specific channel can be inserted into a running sequence
without disturbing that sequence. All requests are arbitrated according to the priority
level assigned to them.
Data reduction features reduce the number of required CPU access operations allowing
the precise evaluation of analog inputs (high conversion rate) even at a low CPU speed.
Result data can be reduced by limit checking or accumulation of results.
The Peripheral Event Controller (PEC) can be used to control the A/D converters or to
automatically store conversion results to a table in memory for later evaluation, without
requiring the overhead of entering and exiting interrupt routines for each data transfer.
Each A/D converter contains eight result registers which can be concatenated to build a
result FIFO. Wait-for-read mode can be enabled for each result register to prevent the
loss of conversion data.
In order to decouple analog inputs from digital noise and to avoid input trigger noise,
those pins used for analog input can be disconnected from the digital input stages. This
can be selected for each pin separately with the Port x Digital Input Disable registers.
The Auto-Power-Down feature of the A/D converters minimizes the power consumption
when no conversion is in progress.
Broken wire detection for each channel and a multiplexer test mode provide information
to verify the proper operation of the analog signal sources (e.g. a sensor system).
