6. Bus Controller
Pin Wait Insertion: Setting the WAITE bit in BCR to 1 enables wait insertion by means of the
WAIT pin. When external space is accessed in this state, a program wait is first inserted. If the
WAIT pin is low at the falling edge of φ in the last T
the WAIT pin is held low, T
This is useful when inserting four or more T
different external devices.
The WAITE bit setting applies to all areas. Pin waits cannot be inserted in DRAM space.
Figure 6.15 shows an example of the timing for insertion of one program wait state in 3-state
space.
