1138I–FPSLI–1/08
General AVR/FPGA I/O Select Procedure
I/O select depends on the FISCR register setup and the FISUA..D register written to or read
from.
The following FISCR setups and writing data to the FISUA..D registers will result in the shown
I/O select lines and data presented on the 8-bit AVR–FPGA data bus.
Table 4-5.
