FT4232H QUAD HIGH SPEED USB TO MULTIPURPOSE UART/MPSSE IC

Datasheet Version 2.05

Clearance No.: FTDI#78

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”.
