Configuring the USB to I2C Adapter

An onboard USB2ANY acts as a USB adapter to the PMIC. This adapter allows I2C communication to the host PC as well as GPIO assertion and fault monitoring. By default, the onboard MSP430 is powered by the 5 V from the uUSB cable and a discrete 3.3V LDO. Additional configurations are allowed by asserting jumpers J1 and J7, shown in Table 4-1and Table 4-2. The onboard adapter must have power applied through a valid configuration.

Table 4-1 I2C pull-up supply selection (J7)
Jumper Pin Selection Description
Pins 1 and 2 (Default) External 3.3V LDO supplies the I2C pins.
Pins 3 and 4 BUCK2 output (VBUCK2) supplies the I2C pins.

Table 4-2 PMIC supply selection (J1)
Jumper Pin Selection Description
Pins 1 and 2 VSYS supplied by external power supply (EXTPWR)
Pins 2 and 3 (Default) VSYS supplied by 5 V from uUSB cable (5VUSB)

The following jumpers in Table 4-3 connect the USB adapter to PMIC functional pins. These can be disabled to GND for flexibility.
