When the BGS12 starts up, all GPIO lines states are described in Section 3.3.3. Therefore, it
is recommended to connect external pull-up or pull-down resistors to all GPIO lines you want
to use as output.
The power supply domain voltage level for GPIO5 to GPIO10 is 2.8V. I2CCLK (GPIO9) and
I2CDAT (GPIO10) require an external pull-up resistor.
The following figure shows the startup behavior of the GPIO interface.
For output and input states see Table 7
