Name
All timing references to SDCLK are given to its rising edge when bit 3 of the SDRAM control register is 0.
SDRAM Interface Timing Specifications
SDCLK to address output A[22:0] valid

SDCLK to SDCS invalid (output hold)
SDCLK to A10_PRECHG valid
SDCLK to A10_PRECHG invalid (output hold)
SDCLK to data output (D[31:0]) high impedance
Data input (D[31:0]) valid to SDCLK (setup) (pipeline mode, SDRAM control register b4
= 1)
Data input (D[31:0]) valid to SDCLK (setup) (straight-through mode, SDRAM control
register b4 = 0)
SDCLK to data input (D[31:0]) invalid (hold)
shows SDRAM timings listed in
lists SDRAM interface timings.
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.
