AT94KAL Series FPSLIC
Table 4-4.
Note:
In summary, 16 select signals are sent to the FPGA for I/O addressing. These signals are
decoded from four base I/O Register addresses (FISUA..D) and extended to 16 with two bits
from the FPGA I/O Select Control Register, XFIS1 and XFIS0. The FPGA I/O read and write sig-
nals, FPGAIORE and FPGAIOWE, are qualified versions of the AVR IORE and IOWE signals.
Each will only be active if one of the four base I/O addresses is accessed.
Reset: all select lines become active and an FPGAIOWE strobe is enabled. This is to allow the
FPGA design to load zeros (8’h00) from the D-bus into appropriate registers.

FISUB $15 ($35)
FISUC $16 ($36)
