A Side
The A side is partitioned into Program memory and Data memory:
Table 3-1.
• Program memory is 16-bit words.
• Program memory address $0000 always starts in the highest two SRAMs (n - 1, n) [SRAMn -
• System configuration determines the higher addresses for program memory:
• Extended program memory is always lost to extended data memory from SRAM2/3 down to
• Data memory is 8-bit words.
• Data memory address $0000 always starts in SRAM0 (SRAM labels are for layout, the
• System configuration determines the higher address for data memory:
• Extended data memory is always lost to extended program memory from SRAM7 up to
1 (low byte) and SRAMn (high byte)] (SRAM labels are for layout, the addressing scheme is
transparent to the AVR PC).
SRAM6/7, see
addressing scheme is transparent to AVR data read/write).
