The TPS65230 and TPS65231 can be controlled either through parallel I/Os or through I2C interface. When the
pull-up resistor on the USBFLAG2/nINT pin is connected to a 3.3-V or lower supply the I2C interface is disabled
and the device is controlled through parallel I/O pins only. With the pull-up resistor connected to 6 V the I2C
interface is enabled and the device is controlled by writing to the control registers. Any fault or abnormal
operating condition is flagged by the interrupt pin. The interrupt is cleared by reading the status register via the
I2C interface.
