3.3 CBUS Signal Options
The following options can be configured on the CBUS I/O pins. CBUS signal options are common to both
package versions of the FT201X. These options can be configured in the internal MTP memory using the
software utility FT_PROG, which can be downloaded from the FTDI Utilities (www.ftdichip.com). The
default configuration is described in Section 9.

FT201X USB I2C SLAVE IC Datasheet
IO Pad is tri-stated
Output a constant 1
Output a constant 0
Output is low after the device has been configured by
USB, then high during USB suspend mode. This output can
be used to control power to an external logic P-Channel
logic level MOSFET switch. Enable the interface pull-down
option when using the PWREN# in this way.
Goes low during USB suspend mode. Typically used to
power down an external logic.
24 MHz Clock output.*
12 MHz Clock output.*
6 MHz Clock output.*
CBUS bit bang mode option. Allows up to 4 of the CBUS
pins to be used as general purpose I/O. Configured
individually for CBUS0, CBUS1, CBUS2 and CBUS3 in the
internal MTP
AN232R-01, available from FTDI website
(www.ftdichip.com) describes in more detail how to use
CBUS bit bang mode.
Battery charge Detect, indicates when the device is
connected to a dedicated battery charger host. Active high
output.
Inverse of BCD Charger (open drain)
Synchronous and asynchronous bit bang mode WR#
strobe output.
Synchronous and asynchronous bit bang mode RD# strobe
output.
Transmit buffer empty, used to indicate to
device status of the FT201EX transmit buffer
Receive buffer full, used to indicate to
status of FT201EX receive buffer
