Description
Connects internal 3.3V regulator to VCCIO. This restricts signal drive to only 3.3V
level signals.
Disconnects internal 3.3V regulator connection to VCCIO. This mode allows for the
supply of 1.8V-3.3V power from an external power supply, thus allows the
processing of signals with logic levels between 1.8V and 3.3V. VCCIO can be
adjusted to match the interface requirements of external circuitry.
Description
Connects VBUS to VCC. This mode is known as “USB-Powered” mode.
Disconnects VBUS to VCC. This allows the supply of power from an external power
supply. This mode is known as “Self-Powered” mode.
