The electronic versions of the dedicated schematics can be enlarged to a far greater degree than
shown in the printed version of this manual or even in the electronic version of this manual, hence
the interested reader is referred to the dedicated schematics to see the appropriate level of detail.

PLL Parts/Usage
Instructions for PLL on Creative Development Board
IGLOO2 and SmartFusion2 M2GL025 devices have up to six fabric CCC (FAB_CCC) blocks at 3.3V
and a dedicated PLL associated with each CCC to provide flexible clocking to the FPGA fabric
portion of the device. The user has the freedom to use any of the eight PLLs and CCCs to generate
the fabric clocks and the internal HPMS clock from the base fabric clock (CLK_BASE). There is
also a dedicated CCC block for the HPMS (HPMS_CCC) and an associated PLL (MPLL) for HPMS
clocking and de-skewing the CLK_BASE clock. The fabric alignment clock controller (FACC), part
of the HPMS CCC, is responsible for generating various aligned clocks required by the HPMS for
correct operation of the HPMS blocks and synchronous communication with the user logic in the
FPGA fabric.

Mini USB Connector for Power, JTAG and UART Connectivity
The Mini USB Connector is used to power the BB as well as provide an embedded FlashPro5
interface to the Microsemi Libero and SoftConsole tools. More information and downloads for Libero
and SoftConsole can be found here:
http://www.microsemi.com/products/fpga-soc/design-resources/design-software
The mini USB can power the board up to 500mA. The EEPROM that is connected to the FTDI device
ss programmed so that Port A of the FTDI device is recognized as an embedded FlashPro5.
The FTDI USB to serial device provides four separate interfaces. Port A is used for a JTAG
connection to the FPGA, Port C is used as a UART interface to the FPGA. Ports B and D are
unused. When connecting a computer to the baseboard, four separate COM ports are recognized.
The third port in the group of four will be the UART port. This is important when using a console port
program such as HyperTerm or TeraTerm.
