Register 0x07 Field Descriptions Bit Field Type Reset Description 7-5 OP IF MAPPER R/W 000 Output interface mapper. This register contains the proper output interface bit mapping for the different interfaces. The interface bit mapping is internally loaded from e-fuses and also requires a fuse load command to go into effect (0x13, D0). Register 0x07 along with the E-Fuse Load (0x13, D0) needs to be loaded first in the programming sequence since the E-Fuse load resets the SPI writes. After initial reset the default output interface variant is loaded automatically from fuse internally. However when reading back this register reads 000 until a value is written using SPI. 001: 2-wire, 18 and 14-bit 010: 2-wire, 16-bit 011: 1-wire 100: 0.5-wire others: not used 4 0 R/W 0 Must write 0 3 OP IF EN R/W 0 Enables changing the default output interface mode (D2-D0). 2-0 OP IF SEL R/W 000 Selection of the output interface mode. OP IF EN (D3) needs to be enabled also. After initial reset the default output interface is loaded automatically from fuse internally. However when reading back this register reads 000 until a value is written using SPI. 011: 2-wire 100: 1-wire 101: 0.5-wire others: not used ADC3683-SP SBASAB5 – MARCH 2024 www.ti.com 52 Submit Document Feedback Copyright © 2024 Texas Instruments Incorporated Product Folder Links: ADC3683-SP |
