PROM Interface Signals
The PROM interface is a low speed I/O port that allows the C-5 NP to communicate
through external logic to PROM. The PROM clock is
maximum PROM size is 4MBytes x 16, and configuration is required. The PROM signals are
listed in

The application is required to provide an external shift register with parallel-in and
parallel-out capabilities, and a parallel load register. Both devices should be

When load is asserted on a positive clock
edge, the external logic performs a parallel
load. On each positive clock edge when
load is de-asserted, the shift registers shift.
