C.3 FPGA I/O Registers
The Advantech MIC-3332 FPGA communicates with main I/O spaces. The LPC unit
is used to interconnect the Intel CM236 LPC signals. This chapter will list down all
registers with a short description off the register interface. A detailed explanation can
be found in the regarding function block description.
