If the bit is set towards the 'ON' text on SW40, that particular line is connected to ground. This makes
the corresponding line to be grounded. If the bit is set towards the numeric text (away from the 'ON'
text) on SW40, the corresponding line is pulled high to VIO5.
Booting Options
EZ-USB FX3 can load boot images from various sources selected by the configuration of the
PMODE pins. The boot options for FX3 are as follows:

Note F = floating
The FX3 device can boot from the EEPROM connected to its I2C interface. To enable I2C EEPROM
boot, the PMODE [2:0] signals need to be set based on
the PMODE [2:0] signals is given here.
