Wait Mode in Areas Where Wait-State Controller is Disabled
External three-state access areas in which the wait-state controller is disabled (ASTn = 1, WCEn =
0) operate in pin wait mode 0. The other wait modes are unavailable. The settings of bits WMS1
and WMS0 are ignored in these areas.
Pin Wait Mode 0: Wait states can only be inserted by WAIT pin control. During access to an
external three-state-access area, if the WAIT pin is low at the fall of the system clock ( ) in the T
state, a wait state (T
until the WAIT signal goes high. Figure 6.12 shows the timing.
