6.6 Pin connect block
The pin connect block allows selected pins of the microcontroller to have more than one
function. Configuration registers control the multiplexers to allow connection between the
pin and the on chip peripherals. Peripherals should be connected to the appropriate pins
prior to being activated, and prior to any related interrupt(s) being enabled. Activity of any
enabled peripheral function that is not mapped to a related pin should be considered
undefined.
6.7 External memory controller
The external Static Memory Controller is a module which provides an interface between
the system bus and external (off-chip) memory devices. It provides support for up to four
independently configurable memory banks (16 MB each with byte lane enable control)
simultaneously. Each memory bank is capable of supporting SRAM, ROM, flash EPROM,
burst ROM memory, or some external I/O devices.
Each memory bank may be 8-bit, 16-bit, or 32-bit wide.
