I am in the process of learning how to use the
ADuC81[46] from Analog Devices. While doing so,
I am putting together my notes which are available
at the moment at http://friedtj.free.fr/aduc816.pdf.

Now the questions:
1/ The ADuC814 ADC example code uses an interrupt to
detect the A/D end of conversion. What bit should I
read to detect the end of conversion without interrupt
(ie just a loop reading this bit until completion of
the conversion) ?
2/ The ADuC816 master SPI example code uses
interrupts. I wish to port the program I have written
for the ADuC814 to access a MultiMediaCard to the
ADuC816. Is there any example code of SPI access for
the ADuC816 which does NOT use interrtupts (either
web/to be sent to me by email) ?

In general, is there any decend documentation of
these microcontrollers available on the web ? The
ADuC814 only comes with a very basic datasheet which
doesn't even describe the function of the registers ...

Thanks, Jean-Michel
