16-BIT CMOS MICROCOMPUTER
PRELIMINARY
Notice: This is not a final specification.
Some parametric limits are subject to change.
Fig. 11 Relationship between wait bit, wait selection bit, and access time
Wait bit
As shown in Figure 11, when the external memory area is accessed
with the wait bit (bit 2 of the processor mode register 0 at address
5E
16
) 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
5F
16
).
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”.
Access to internal memory area is always performed in the no wait
mode regardless of the wait bit.
The processor modes are described below.
Fig. 10 External memory area for microprocessor mode
(1) Microprocessor mode [10]
The microcomputer enters the microprocessor mode after connecting
the CNVss pin to Vcc and starting from reset.
RDE
is the output pin for the read enable signal
(RDE)
.
RDE
is “L” during the data read term in the read cycle. When the
internal memory area is read,
RDE
can be fixed to “H” by setting the
signal output disabe selection bit (bit 6 of the oscillation circuit control
register 0) to “1”.
