| BIT | FIELD | TYPE | DEFAULT | DESCRIPTION |
|---|---|---|---|---|
| 7 | SEL3P3V | R/W | 0x0 | 3.3V I/O Select on I2C_SCL, I2C_SDA and INTB
pins. 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. |
| 6 | IO_SUPPLY _MODE_OV |
R/W | 0x0 | Override I/O Supply Mode bit 0: Detected I/O voltage level will be used for both SEL3P3V and IO_SUPPLY_MODE controls. 1: Register values written to the SEL3P3V and IO_SUPPLY_MODE fields will be used. |
| 5:4 | IO_SUPPLY_MODE | R/W | 0x0 | I/O Supply Mode 00: 1.8V 01: Reserved 10: Reserved 11: 3.3V If IO_SUPPLY_MODE_OV is 0, a read of this register will return the detected I/O voltage level. |
