ROM Mode: The ROM mode uses the same principal as the RAM modes, but without the Write port. Pre-loading is
accomplished through the programming interface during configuration.
PFU Modes of Operation
Slices can be combined within a PFU to form larger functions. Table 2-4 tabulates these modes and documents the
functionality possible at the PFU level.
