The software assumes the following scheme for connecting the Flash-
EPROM to the IBM PPC405xxx. Please contact us, if you have used a
different method.

1.) PER_R/W# is set to output with high level during read cycles and is
2.) Only PER_WBE1# is switched as write strobe.
3.) All other signals are hold static during flash programming. The state
set to output with low level during write cycles.
