Auto Configuration
Disabling this option allows the values for the other
parameters to be changed. Enabling it will restrict you from making any
changes.
Cache
Wait State
determines the number of cycle times to
be inserted when CPU reads data to cache. The setting depends on the
speed of the CPU and SRAM. If the CPU is of high speed, the time re-
quired by SRAM to process data will need an extension, with the excep-
tion of some
that are fast enough to catch up with the speed of
the CPU. The available options are:
. 3-2-2-2

Cache Write Hit Wait State
setting of this parameter makes no dif-
ference from that of the SRAM Read. This option sets the number of
wait states to be added on writes to cache memory. Fewer wait states
are recommended to improve the system performance. Check the CPU
speed and SRAM before changing the default value. The available op-
tions are listed below.

DRAM Wait State
determines the number of wait states to be in-
serted when the CPU reads data into the local DRAM. Fewer wait
states are recommended to improve the system performance. The fol-
lowing are the available options.
