(b)
The initial data read/write operation is the same as a normal read/write operation. That is, when
the WAIT signal is low two cycles before the end of the wait cycles (Tend), external wait cycles
are inserted. After the WAIT signal has gone high, the wait cycles end (Tend) two cycles later.
In the second and subsequent read accesses, the page wait cycle is extended if the WAIT signal is
low two cycles before the end of the page access wait cycle (Tend), and the page wait cycles end
two cycles after the WAIT signal has gone high.
Figure 9.6 shows an example of external wait timing for page read access using longword (32-bit)
access to a 16-bit channel.
