Extended Hold Time on Read Accesses
For devices that require a long disconnection time from the data bus on read accesses, the bit EHTR in the
corresponding OR register can be set. In this case any MPC561/MPC563 access to the external bus
following a read access to the referred memory bank is delayed by one clock cycle unless it is a read access
to the same bank.

Figure 10-18
show the effect of the EHTR bit on memory
controller timing.
Figure 10-15
shows a write access following a read access. Because EHTR = 0, no extra clock cycle is
inserted between memory cycles.
