1. The Soft “BOOT BLOCK” is an area of memory that is first loaded when the part is powered up
2. The lower portion of the Data memory is not shared between the AVR and FPGA. The AVR
and configured. The remainder of the memory can be reprogrammed while the device is in
operation for switching functions in and out of memory. The Soft “BOOT BLOCK” can only be
programmed by a full device configuration on power-up.
uses addresses $0000 - $001F for the AVR CPU general working registers. $001F - $005F are
the addresses used for Memory Mapped I/O and store the information in dedicated registers.
Therefore, on the FPGA side $0000 - $005F are available for data that is only needed by the
FPGA.
