Fig. 60 Relationship between wait bit, wait selection bit, and access time
Wait bit
As shown in Figure 60, when the external memory area is accessed
with the wait bit (bit 2 of the processor mode register 0 at address
5E16) cleared to “0”, the access time can be extended compared with
no wait (the wait bit is “1”).
The access time is extended in two ways and this is selected with the
wait selection bit (bit 0 of the processor mode register 1 at address
5F16).
When this bit is “1”, the access time is 1.5 times compared to that for
no wait. When this bit is “0”, the access time is twice compared to
that for no wait.
At reset, the wait bit and the wait selection bit are “0”.
The accessing of internal memory area is always performed in the
no wait mode regardless of the wait bit.
The processor modes are described below.
