Functional Description
The CY7C269 is a 8K x 8 registered diagnostic PROM. It is
organized as 8,192 words by 8 bits wide, and has both a pipe-
line output register and an onboard diagnostic shift register.
The device features a programmable initialize byte that may
be loaded into the pipeline register with the initialize signal.
The programmable initialize byte is the 8,193rd byte in the
PROM, and may be programmed to any desired value.
