3.3V I/O Select on pins INTB, I2C, GPIO
0: 1.8V I/O Supply
1: 3.3V I/O Supply
If IO_SUPPLY_MODE_OV is 0, a read of this
register will return the detected I/O voltage
level.
0
Override I/O Supply Mode bit
If set to 0, the detected voltage level is used
for both SEL3P3V and IO_SUPPLY_MODE
controls.
If set to 1, the values written to the SEL3P3V
and IO_SUPPLY_MODE fields is used.
0x0
I/O Supply Mode
00: 1.8V
11: 3.3V
If IO_SUPPLY_MODE_OV is 0, a read of this
register will return the detected I/O voltage
level.
0x9

0x0
GPIO Pin Status
This register reads the current values on each
of the 8 GPIO pins. Bit 7 reads GPIO7 and bit
0 reads GPIO0.
