Automatic Flow Control (Hardware Mode): When in
Hardware Mode, set high to enable automatic flow control
pause and backpressure application. In the software
mode this pin has no effect and the rate selection is
controlled by the SU.GCR register.
Note that in the 100-pin CSBGA (DS33ZH11) package,
this pin is internally tied to V
SDRAM Data Bus (Bits 0 through 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
DS33Z11. No user programming for SDRAM buffering is
required.
SDRAM Address Bus 0 through 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
