Description
7-2
Reserved
1
Read/Write Extended Mode Enable. When set to 1, enables the separation of the I/O read and write
transactions from pins XRD & XWR to pins XIORD & XIOWR, leaving the memory and FWH transactions to be
routed to XRD and XWR.
0: Disabled (default)
1: Enabled
0
Latch Address Mode Enabled. When set to 1, enables three phases of addresses to be latched on the data
pins. Reset value of this bit is set by the XCNF2-0 strap inputs. See Section 1.5.11 for the definition of this
setting.
