3.4.2 FT4232H pins used in a Synchronous or Asynchronous Bit-Bang
The FT4232H channel A, B, C or channel D can be configured as a bit-bang interface. There are two types
of bit-bang modes: synchronous and asynchronous.
When configured in any bit-bang mode (synchronous or asynchronous), the pins used and the
descriptions of the signals are shown in
Table 3.6 Channel A,B,C and Channel D Synchronous or Asynchronous Bit-Bang Configured Pin
