Power source for programming embedded eFUSE. It should be kept
floating or 0V when not in programming mode
VBUS_DET
VBUS detection input. It is a +5.0V tolerant pin
DIO12, Digital Input/Output Pin 12.
This pin can be configured as one of the following three functions via
embedded eFUSE or external EEPROM.

DSRN, Data Set Ready, can be enabled via USB command for UART
interface.
Table 3.1 FT260 Pin Description
**If VCCIN is supplied with 3.3V power input, then VOUT3V3 and VCCIO must also be driven with this
3.3V power source. For details refer to Section 7.3.
