External Wait
1354D–ATARM–08/02
Figure 19. Data Float Output Time
Notes:
The NWAIT input can be used to add wait states at any time. NWAIT is active low and is
detected on the rising edge of the clock.
If NWAIT is low at the rising edge of the clock, the EBI adds a wait state and changes
neither the output signals nor its internal counters and state. When NWAIT is de-
asserted, the EBI finishes the access sequence.
The NWAIT signal must meet setup and hold requirements on the rising edge of the
clock.
