Bit Bang Mode Availability for the FT232R and FT245R Application Note

PublishTime：2024-07-04

●This document describes the 3 Bit Bang Modes available with the FTDI FT232R and FT245R devices. It also gives examples on how to use these 3 modes. ●Introduction ■Bit Bang mode is a special FT232R and FT245R device mode that changes the 8 IO lines into an 8 bit bi-directional data bus. There are three types of Bit Bang mode: ▲Asynchronous Bit Bang Mode , which is the same as the FTDI BM and C chip-style Bit Bangmode, with the addition of Read and Write strobes in the case of the FT232R. ▲Synchronous Bit Bang Mode, where data is only read from the device when the device is written to. This is the same as the FT2232 Synchronous Bit Bang mode. ▲CBUS Bit Bang Mode, a new 4-bit version of Bit Bang mode is available on the FT232RCBUS pins. ■Asynchronous and Synchronous Bit Bang modes are enabled by driver commands, while CBUS Bit Bang must be set up in the device EEPROM (this can be done using the FT_PROG utility) before it can be enabled with a driver command.
