Channel A
3.4.5 FT2232H pins used in an MPSSE
The FT2232H channel A and channel B each have a Multi-Protocol Synchronous Serial Engine (MPSSE).
Each MPSSE can be independently configured to a number of industry standard serial interface protocols
such as JTAG, I2C or SPI, or it can be used to implement a proprietary bus protocol. For example, it is
possible to use one of the FT2232H‟s channels to connect to an SRAM configurable FPGA such as supplied
by Altera or Xilinx. The FPGA device would normally be un-configured (i.e. have no defined function) at
power-up. Application software on the PC could use the MPSSE to download configuration data to the
FPGA over USB. This data would define the hardware function on power up. The other FT2232H channel
would be available for another function. Alternatively each MPSSE can be used to control a number of
GPIO pins. When configured in this mode, the pins used and the descriptions of the signals are shown
