PRODUCTION DATA
BIT | FIELD | TYPE | DEFAULT | DESCRIPTION |
---|---|---|---|---|
7 | SEL3P3V | R/W | 0 | 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. |
6 | IO_SUPPLY_MODE_OV | R/W | 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. |
5:4 | IO_SUPPLY_MODE | R/W | 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. |
3:0 | RESERVED | - | 0x9 | Reserved |
