states).
The memory cycle time wait states can be programmed in increments of one EBC
system clock (LCLKO) within a range from 0 to 15 (default value after reset) via the
’MCTC’ bit field in the LBI Configuration register LCONF. (15-<MCTC>) waitstates will
be inserted.
Figure 26
The external bus cycles of the EBC can be extended for a memory or peripheral, which
cannot keep pace with the EBC’s maximum speed, by introducing wait states during the
access (see figure above).
The minimum LRD/LWR strobe active length is 2 LBI clock cycles (with zero MCTC wait
