38 / 97 page  ADBMS2950B Data Sheet Rev. 0 | Page 38 of 97 The x indicates the bits that can be either 0 or 1. Any combination is valid, and the ADBMS2950B responds the same way if the command PEC matches the command bytes. RDALL commands are not available on the isoSPI daisy-chains. For more details, see the Communication Protocol section. Table 50. ADV Parameter Bits Name Type Value Description OW PAR V1ADC and V2ADC open-wire test current injection enable. 00 V1ADC and V2ADC open-wire source off. 01 Current injected into V1ADC MUXP for measurements V1 to V8. Current injected into V2ADC MUXP for measurements V9 to V10. Do not use OW=0b01 in combination with VCH=9, see note below. 10 Current injected into V1ADC MUXN (Pins selected by VS1 to VS8 configuration) for measurements V1 to V8. Current injected into V2ADC MUXN (Pins selected by VS9 to VS10 configuration) for measurements V9 to V10. 11 Reserved. VCH PAR V1ADC and V2ADC channel select. ≤8 Single Measurement, see Table 57. ≥9 Multi Measurement, see Table 58. Note that do not use open-wire test current injection on MUXP (OW=0b01) in combination with VCH=9. This injects current in an internal divided VREF2 reference path, which may cause a false trigger of the VDDUV flag. Multichannel open-wire test current injection can be used on MUXN (OW=0b10) issued with any VCH setting or on MUXP (OW=0b01) with VCH=10 to VCH=15. Single-channel open-wire diagnostic measurements can be issued with any OW and VCH setting. Table 51.
