R/W —Read/Write
This field causes a chip select to be asserted only for a read, only for a write, or for both read and write.
Refer to the following table for options available.
STRB —Address Strobe/Data Strobe
0 = Address strobe
1 = Data strobe
This bit controls the timing for assertion of a chip select in asynchronous mode. Selecting address
strobe causes chip select to be asserted synchronized with address strobe. Selecting data strobe caus-
es chip select to be asserted synchronized with data strobe.
DSACK —Data and Size Acknowledge
This field specifies the source of DSACK in asynchronous mode. It also allows the user to adjust bus
timing with internal DSACK generation by controlling the number of wait states that are inserted to op-
timize bus speed in a particular application. The following table shows the DSACK field encoding. The
fast termination encoding (1110) is used for two-cycle access to external memory.
