Firmware modules.
At the firmware level, this board is made up of the following modules:
- PIC microcontroller: manages board communications and start-up.
- FPGA programmable device: manages the alarms and the TDM bus.
The firmware versions can be brought up to date by using the ”BC2000D Firmware Upgrade”
software application.
