7.4.1 Mode Select Configuration Settings (MODE_SEL[1:0])
Configuration of the device may be done via the MODE_SEL[1:0] input pins, or via the configuration register bits. A pull-up resistor and a pull-down resistor of suggested values may be used to set the voltage ratio of the MODE_SEL[1:0] inputs. See Table 7 and Table 8. These values will be latched into register location during power-up:
Table 6. MODE_SEL[1:0] Settings
| MODE | SETTING | FUNCTION |
|---|---|---|
| OLDI_DUAL: OpenLDI Interface | 0 | Single-pixel OpenLDI interface. |
| 1 | Dual-pixel OpenLDI interface. | |
| REPEATER: Configure Repeater | 0 | Disable repeater mode. |
| 1 | Enable repeater mode. | |
| MAPSEL: OpenLDI Bit Mapping | 0 | OpenLDI bit mapping. |
| 1 | SPWG bit mapping. | |
| COAX: Cable Type | 0 | Enable FPD-Link III for twisted pair cabling. |
| 1 | Enable FPD-Link III for coaxial cabling. |

The strapped values can be viewed and/or modified in the following locations:
- OLDI_DUAL : Latched into OLDI_IN_MODE (0x4F[6], inverted from strap value).
- REPEATER : Latched into TX_RPTR (0xC2[5]).
- MAPSEL : Latched into OLDI_MAPSEL (0x4F[7]).
- COAX : Latched into DUAL_CTL1[7], COAX_MODE (0x5B[7]).
