Wait Modes in Areas Where Wait-State Controller is Enabled
External three-state access areas in which the wait-state controller is enabled (ASTn = 1, WCEn =
1) can operate in pin wait mode 1, pin auto-wait mode, or programmable wait mode, as selected by
bits WMS1 and WMS0. Bits WMS1 and WMS0 apply to all areas, so all areas in which the wait-
state controller is enabled operate in the same wait mode.
Pin Wait Mode 1: In all accesses to external three-state-access areas, the number of wait states
(T
clock ( ) in the last of these wait states, an additional wait state is inserted. If the WAIT pin
remains low, wait states continue to be inserted until the WAIT signal goes high.
Pin wait mode 1 is useful for inserting four or more wait states, or for inserting different numbers
of wait states for different external devices.
If the wait count is 0, this mode operates in the same way as pin wait mode 0.
Figure 6.13 shows the timing when the wait count is 1 (WC1 = 0, WC0 = 1) and one additional
wait state is inserted by WAIT input.
