2.1

Path (outline) data input port (continued)

• POINT FIFO memory map

2.2

Gray-scale data output port (RASTER FIFO)

Memory port used for output of the gray-scale data generated by the MN5572. This port allows 64 double-

word values to be read at one time. If more than 64 double-word values must be read, the read operation must be

split into multiple operations. The RASTER FIFO has a total capacity of 256 double-word values.

• Local 32 and PCI mode

• Local 16 mode

Data is transferred in the order high-order bits first, low-order bits later.
