6.3.5
CSACRH and CSACRL select whether or not the assertion period of the basic bus interface chip
select signals (CSn) and address signals is to be extended. Extending the assertion period of the
CSn and address signals allows flexible interfacing to external I/O devices.

Description
CS and Address Signal Assertion Period Control 1
These bits specify whether or not the T
be inserted (see figure 6.3). When an area for
which the CSXHn bit is set to 1 is accessed, a
one-state T
address signals are asserted, is inserted before
the normal access cycle.
0: In area n basic bus interface access, the CSn

Description
CS and Address Signal Assertion Period Control 2
These bits specify whether or not the T
shown in figure 6.3 is to be inserted. When an
area for which the CSXTn bit is set to 1 is
accessed, a one-state T
CSn and address signals are asserted, is inserted
after the normal access cycle.
