Start AD continuous sampling
The A/D continuous measurement allows the user to sample one or more
channels at regular intervals (1s - 10µs). The measured values are stored
by the module into the internal FIFO and can be retrieved there during and
after the sampling process. The values are buffered in the FIFO until they
either have been fetched or a new sampling command has been called.
To stop the continuous measurement the command „stop continuous
A/D sampling" must be sent to the module.
Attention: it must be ensured that the FIFO can be emptied quickly
enough since the FIFO is limited to 10,000 readings. Furthermore, no
EXDUL information register (e.g. UserA, UserB) may be written during
the processing.
