“The following are DPLD outputs (chip selects) for EPROM, SRAM & I/O Port
rs0,es0,es1,es2,es3,csiop node;
“The following are Page Register outputs; they can be used as a data
“l(fā)atch for GPLD input if paging is not needed

“Use the pgr3 bit to determine if the system is in the flash program mode or the
“operational mode. When this bit is a one, the system is in the flash program mode.
“DEFINITIONS
X = .x.;
clk = .c.;
page = [pgr1,pgr0];
program = pgr3;
“Don’t care

“address a7-a2 are not available as inputs to the GPLD unless
“it has been assigned to Port A pins

EQUATIONS
“If a7-a2 are assigned to Port A, they need to be latched by ALE in the
“l(fā)ogic equations that follow:
“a7.le = ale;
a6.le = ale;
