9.0 Timing and Control
(Continued)
Figure 10 shows the timing for memory read (other than
opcode fetchs) and write cycles with and without a wait
state. The RD stobe is widened by
t
2
(half the machine
state) for memory reads so that the actual latching of the
input data occurs later.
Figure 11 shows the timing for input and output cycles with
and without wait states. The CPU automatically inserts one
wait state into each I/O instruction to allow sufficient time
for an I/O port to decode the address.
