Access
during a read cycle whenever DTA goes low. When
writing to the MT8986, one write operation is
sufficient. However, when reading MT8986, two read
operations with the same address are required, with
the second being valid.
Enough time need to be provided between two CPU
accesses to allow the first access to complete; i.e., to
allow for an internal MT8986 reaction over the first
RD/WR access. For a read operation, a minimum of
1220 ns have to be guaranteed between two
successive accesses. For write, at least 800 ns has
to be respected.
