Default Value
Notes
Bus Powered
100mA
Define whether the power source is from the USB bus or a local
source.
The max power that will be drawn from VBUS when using bus
power. Range from 0~500mA. If the power source is defined as
self-powered, it must be set as 0mA.

Define if the FT260 supports remote wake up or not.
The GPIO2 pin can be set as one of the alternative functions:
- GPIO2
- PWREN# (low active), device ready indicator
- TX_LED, UART TX transferring indicator
- SUSPOUT_N, USB suspend low-active indicator.
The GPIOA pin can be set as one of the alternative functions:
- GPIOA
- TX_LED, UART TX transferring indicator
- TX_ACTIVE
The GPIOG pin can be set as one of the alternative functions:
- GPIOG
- PWREN# (low active), device ready indicator
- RX_LED, UART RX receiving indicator
- BCD_DET, Battery Charger Detection indicator
Adjustable drive strength for UART related pins TXD/RXD,
CTS/RTS, DTR/DSR, TX_ACTIVE. Drive strength can be set as
4mA, 8mA, 12mA and 16mA
Adjustable drive strength for GPIO related pins GPIO0, GPIO1,
GPIO2, GPIO3, GPIO4, and GPIO5. Drive strength can be set as
4mA, 8mA, 12mA and 16mA
Battery Charger Detection function can be disabled on
BCD_DET pin.
Adjustable drive strength for BCD_DET pin. Drive strength can
be set as 4mA, 8mA, 12mA and 16mA
Set the polarity on BCD_DET pin for indicating battery charge
detected. Default is set as active-high.
If power saving mode is enable and the FT260 is idle for 5
seconds, it will switch the system clock to 30KHz for saving
power.
The I²C slave address of the target HID-over-I²C device. The
address 0h means no HID-over-I²C device connected.
The start address of the descriptor of the target HID-over-I²C
device.
Define the interrupt trigger type of the target HID-over-I²C
device. It can be: rising edge, falling edge, level-high, level-
low.
