Table 4.1 MPSSE Signal Timings
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 AN2232-02, “Bit Mode Functions for the FT2232”
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:
