C.2 FPGA I/O Registers
The Advantech MIC-3393 FPGA communicates with main I/O spaces. The LPC unit
is used to interconnect the Intel ICH9R LPC signals. The Debug Port Unit is used to
decode POST codes. The Hot-Swap Out-Of-Service LED Control Unit is used to con-
trol the blue LED during Hot-Insert and Hot-Remove. The Drone Mode Unit is used to
disable the CPCI bridge. The other signals in the Miscellaneous Unit are for interfac-
ing with corresponding I/O interface signals.
