Bus Operations Summary
Bus Operations
CE# low and RST# high enable device read operations. The device internally decodes
upper address inputs to determine the accessed block. ADV# low opens the internal
address latches. OE# low activates the outputs and gates selected data onto the I/O
bus.
Bus cycles to/from the P33-65nm device conform to standard microprocessor bus
operations.
the logic levels that must be applied to the device control signal inputs.
Read - Asynchronous Single Word Mode
To perform an asynchronous single word read, an address is driven onto the address
bus, and CE# is asserted. ADV# must be held low throughout the read cycle for TSOP
package. ADV# can either be driven high to latch the address or be held low
throughout the read cycle for Easy BGA package. WE# and RST# must already have
been deasserted. WAIT is set to a deasserted state during single word mode as
determined by RCR.10. CLK is not used for asynchronous single word reads, and is
ignored. After OE# is asserted, the data is driven onto DQ[15:0] after an initial access
time t
If only asynchronous reads are to be performed, CLK should be tied to a valid V
WAIT signal can be floated and ADV# must be tied to ground.
Refer to the following waveforms for more detailed information.

Read - Asynchronous Page Mode (Easy BGA)
To perform an asynchronous page read, an address is driven onto the address bus, and
CE# and ADV# are asserted. WE# and RST# must already have been deasserted.
WAIT is set to a deasserted state during asynchronous page mode and single word
mode as determined by RCR.10. ADV# can be driven high to latch the address, or it
must be held low throughout the read cycle. CLK is not used for asynchronous page-
mode reads, and is ignored. After OE# is asserted, the data is driven onto DQ[15:0]
after an initial access time t
