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.

Description
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 memory. A separate application note,
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 I2C master
device status of the FT201EX transmit buffer
Receive buffer full, used to indicate to I2C master device
status of FT201EX receive buffer
