Clearance No.: FTDI #199
3.5.7 FT232H Pins Configured as a CPU-style FIFO Interface
The FT232H can be configured in a CPU-style FIFO interface mode which allows a CPU to interface to USB
via the FT232H. This mode is enabled in the external EEPROM.
When configured in this mode, the pins used and the descriptions of the signals are shown in Table 3.12

Tie this pin to VCCIO if not used – otherwise, for
normal operation
The Send Immediate / WakeUp signal combines two
functions on a single pin. If USB is in suspend mode
(PWREN# = 1) and remote wakeup is enabled in the
EEPROM, strobing this pin low will cause the device to
request a resume on the USB Bus. Normally, this can
be used to wake up the Host PC.
During normal operation (PWREN# = 0), if this pin is
strobed low any data in the device RX buffer will be
sent out over USB on the next Bulk-IN request from
the drivers regardless of the pending packet size. This
can be used to optimize USB transfer speed for some
applications.
