4.6 FT4232H Mode Selection
The 4 channels of the FT4232H reset to 4 asynchronous serial UART interfaces. Following a reset, the
required mode can be configured by sending the FT_SetBitMode command (refer to
D2XX_Programmers_Guide) to the USB driver software.
The EEPROM contents have no effect on the selected mode with the exception of selecting the TXDEN for
RS485 mode when asynchronous serial interface has been selected in software. If the device is reset,
then the 4 channels must be reconfigured into the required mode.
Note that the mode of each of the 4 channels is independent of the other channels.
The MPSSE can be configured directly using the D2XX commands. The D2XX_Programmers_Guide is
available from the FTDI website at
http://www.ftdichip.com/Documents/ProgramGuides/D2XX_Programmer's_Guide(FT_000071).pdf
Also the MPSSE command set is fully described in application note AN_108 – “Command Processor
For MPSSE and MCU Host Bus Emulation Modes”.
