QADC64E Legacy Mode Operation
BIU components consist of:
13.5.7.2
The QADC64E supports 8-bit, 16-bit, and 32-bit data transfers, at even and odd addresses. Coherency of
results read (ensuring that all results read were taken consecutively in one scan) is not guaranteed. For
example, if a read of two consecutive 16-bit locations in a result area is made, the QADC64E could change
one 16-bit location in the result area between the bus cycles. There is no holding register for the second
16-bit location. All read and write accesses that require more than one 16-bit access to complete occur as
two or more independent bus cycles. Depending on bus master protocol, these accesses could include
misaligned and 32-bit accesses.
Figure 13-26
paragraphs describe how the three types of accesses are used, including misaligned 16-bit and 32-bit
accesses.

QADC64E Bus Accessing
shows the three bus cycles which are implemented by the QADC64E. The following
Normal accesses from the IMB3 to the QADC64E require two clocks.
However, if the CPU tries to access table locations while the QADC64E is
accessing them, the QADC64E produces IMB3 wait states. From one to
four IMB3 wait states may be inserted by the QADC64E in the process of
reading and writing.
