Section 6 Bus Controller
Pin Auto-Wait Mode: If the WAIT pin is low, the number of wait states (T
WC1 and WC0 are inserted.
In pin auto-wait mode, if the WAIT pin is low at the fall of the system clock ( ) in the T
number of wait states (T
are inserted even if the WAIT pin remains low. Pin auto-wait mode can be used for an easy
interface to low-speed memory, simply by routing the chip select signal to the WAIT pin.
Figure 6.14 shows the timing when the wait count is 1.
