When reading the output data registers after a conversion
sequence, that is, when BUSY goes low, the register pointer is
incremented on the rising edge of the RD signal, as shown in
. However, when reading the conversion results during
the conversion sequence, the pointer is not incremented until a
valid conversion result is in the register to be addressed. In this
case, the pointer is incremented when the conversion has ended
and the result has been transferred to the output data register.
This happens immediately before
EOC goes low, therefore EOC
may be used to enable the register contents onto the data bus,
as described in the
subsection within the
section. The pointer is reset to point
to Register 1 on the rising edge of the
RD signal when the last
conversion result in the sequence is being read. In the example
shown, this means that the pointer is set to Register 1 when the
contents of Register 3 are read.
