Processor Bus Output Timing Specifications
Above 48 MHz, the memory bus may need to be configured for one wait
state. It is the responsibility of the user to determine the actual frequency at
which to insert a wait state since this depends on the access time of SRAM
or SDRAM used in a particular system implementation.
Wait states are inserted for SRAM accesses by programming bits 6–2 of the
chip select option registers.
A wait state is added for SDRAM read accesses by setting bit 4 of the
SDRAM control register.
