SDRAM Data Bus Bits 0 to 31: The 32 pins of the SDRAM data
bus are inputs for read operations and outputs for write operations.
At all other times, these pins are high-impedance.
Note: All SDRAM operations are controlled entirely by the
DS33R11. No user programming for SDRAM buffering is required.
SDRAM Address Bus 0 to 11: The 12 pins of the SDRAM address
bus output the row address first, followed by the column address.
The row address is determined by SDA0 to SDA11 at the rising
edge of clock. Column address is determined by SDA0-SDA9 and
SDA11 at the rising edge of the clock. SDA10 is used as an auto-
precharge signal.
Note: All SDRAM operations are controlled entirely by the
DS33R11. No user programming for SDRAM buffering is required.
SDRAM Mask 0 through 3: When high, a write is done for that
byte. The least significant byte is SDATA7 to SDATA0. The most
significant byte is SDATA31 to SDATA24.
SDRAM CLK Out: System clock output to the SDRAM. This clock
is a buffered version of SYSCLKI.
