To Start A Conversion
If necessary, clear the Analogue Conversion Control Register (ACCR) by
writing 00 to the address Base 2 + 0C
h
.
Set the Analogue Input Select Register (at address Base 2 + 0D
h)
, to the required
channel, gain and input mode.
Allow the settling time (if necessary).
Write to the ACCR to select the trigger source, edge or level trigger, and single
or multiple channels for conversion.
Poll the Analogue Input Status Register (at Base 2 + 0E
h
) for FIFO Not Empty,
or Conversion Complete. Alternatively, interrupts may be used (see section
“Interrupt Selection”).
Limitations to Use
Level triggering of the conversion is provided to allow the rapid monitoring of a
single input channel. It gives a high sample rate (the “burst rate”) for a limited
period, usually until the FIFO is full. Conversions will continue when the FIFO
is full, but the results will not be stored until the FIFO is at least partially empty.
Subsequent conversions will then be stored until the FIFO is again full.
Level triggering provides conversions as fast as the ADC can service them with
no allowance made for the switching and settling times of the multiplexers or
the programmable gain amplifier. Attempting to convert multiple channels
using level control will result in erroneous results because the differing inputs
will not have sufficient time to settle.
