Module
Flash memories are encapsulated within the Flash Memory (FM) Module. Flash control is
accomplished by the I/O to the FM over the peripheral bus, while reads and writes are completed
between the core and the Flash memories.
The primary data RAM port is 32 bits wide. Other data ports are 16 bits.
NOT available on the 56F8157 device.
