4.6 MPSSE Interface Mode Description.
MPSSE Mode is designed to allow the FT2232H to interface efficiently with synchronous serial protocols
such as JTAG, I2C and SPI Bus. It can also be used to program SRAM based FPGAs over USB. The
MPSSE interface is designed to be flexible so that it can be configured to allow any synchronous serial
protocol (industry standard or proprietary) to be implemented using the FT2232H. MPSSE is available on
channel A and channel B.
MPSSE is fully configurable, and is programmed by sending commands down the data stream. These can
be sent individually or more efficiently in packets. MPSSE is capable of a maximum sustained data rate of
30 Mbits/s.
When a channel is configured in MPSSE mode, the IO timing and signals used are shown in Figure 4.7
and Table 4.3 These show timings for CLKOUT=30MHz. CLKOUT can be divided internally to be provide a
slower clock.

MPSSE mode is enabled using Set Bit Bang Mode driver command. A hex value of 2 will enable it, and a
hex value of 0 will reset the device. See application note AN2232L-02, “Bit Mode Functions for the
FT2232D” for more details and examples.
The MPSSE command set is fully described in application note AN_108 – “Command Processor For
MPSSE and MCU Host Bus Emulation Modes”.
The following additional application notes are available for configuring the MPSSE :
