1. This map provides the complete architectural address space definition for the flash. Based on the physical sizes of the
memories implemented for a particular device, the actual address regions used may be smaller. See Flash Memory Sizes
for details.
2. This range varies depending on amount of SRAM implemented for a particular device. See SRAM sizes for details.
NOTE
1. EzPort master port is statically muxed with DMA master
port. Access rights to AIPS-Lite peripheral bridge and
general purpose input/output (GPIO) module address space
is limited to the core, DMA and EzPort.
