Memory Controller
The memory controller generates interface signals to support a glueless interface to external memory and
peripheral devices. It supports four regions, each with its own programmed attributes. The four regions are
controlled by four chip-select signals. Read and write strobes are also provided.
The memory controller operates in parallel with the external bus interface to support external cycles. When
an access to one of the memory regions is initiated, the memory controller takes ownership of the external
signals and controls the access until its termination. Refer to
10.1
The memory controller provides a glueless interface to external EPROM, static RAM (SRAM), Flash
(EEPROM), and other peripherals. The general-purpose chip-selects are available on lines CS0 through
CS3. CS0 also functions as the global (boot) chip-select for accessing the boot Flash EEPROM. The chip
select allows zero to 30 wait states.
