1) Or one of the other chip select signals: SYS_DEVCS0#, SYS_DEVCS1#,
2) These signals are the latched SYS_ADR0..11.
3) SYS_ADR0..23 represent always a cell address. SYS_ADR0 should always

on your board: For normal operation the signal SYS_DQMWE0# must be
connected to the write enable input of the Flash-EPROM. For programming
with the JTAG-Booster the signal SYS_DQMWE1# must be connected to
the Flash-EPROM
In case of programming 8 Bit EPROMs there must be a switch/multiplexer
As a result of the latched addresses only Flash devices with short unlock
vectors are supported. This means that the old AMD 29F010 which needs
the unlock addresses 0x5555 and 0x2AAA are not supported, the newer
versions AM29F010B have short vectors (0x555 and 0x2AAA) and can be
programmed.
Refer to the following table for connecting Flash-EPROMs to the IDT
RC64145:
SYS_DEVCS2#, SYS_DEVCS3#
be connected to the LSB of the device address, regardless of bank width.
