Notes:

1. The Local Memory/Peripheral area of the memory map can be configured for SDRAM, ROM or Peripherals.

2. The Boot ROM and Expansion ROM area of the memory map are intended for use by ROM or Flash-type devices. While locating

volatile SDRAM and SRAM in this region is supported by the controller it is not recommended that these regions be used for this

purpose.
