C.1
Overview
Advantech’s BMC solution combines an NXP LPC1768 ARM Cortex-M3-based 32-bit
microcontroller and a lattice FPGA. The FPGA mainly integrates hardware interfaces
that are available inside the LPC1768, like KCS.
Because MIC-3399 is available both with and without the BMC, some functions will
be implemented redundantly inside the FPGA and BMC. If the BMC is populated, a
simple register inside the FPGA is used to control the function from the BMC. On a
MIC-3399 without BMC, the FPGA controls the function itself in the same way as
before.
C.2

C.3
FPGA I/O Registers
The MIC-3399 FPGA communicates with the main I/O spaces. The LPC unit is used
to interconnect the Intel CM236 LPC signals. The debug port unit is used to decode
POST codes. The hot-swap out-of-service LED control unit is used to control 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 interfacing with the
corresponding I/O interface signals.
