mono interrupt-driven mode (CR0.(3,2) = 0,0)
The mono interrupt-driven conversion mode provides a one-shot conversion. Sampling, conversion, and data
output are all performed in a single cycle. The analog signal is sampled 2 SYSCLKs after the falling edge of RD
(or the rising edge of WR if this is the first sample after configuration) and then converted on the falling edge
of RD. Once the data is ready, INT falls and the data is output to the bus. The rising edge of RD cancels INT
and initiates a read of the data. The data bus is 3-stated when RD goes high. It is not necessary to configure
the converter for each cycle or toggle CS between cycles.
