Product Specification
52
An example of WAIT state operation is illustrated in
Figure
6. In this example, the Chip
Select is configured to provide a single WAIT state. The external peripheral being
accessed drives the WAIT pin Low to request assertion of an additional WAIT state. If the
WAIT pin is asserted for additional system clock cycles, WAIT states are added until the
WAIT pin is de-asserted (High).
