212 / 279 page  System voltage diagnostics L9679P 212/279 DS11627 Rev 7 15 System voltage diagnostics L9679P has an integrated dedicated circuitry to provide diagnostic feedback and processing of several inputs. These inputs are addressed with an internal analog multiplexer and made available through the SPI digital interface with the Diagnostic Data commands. In order to avoid saturation of high voltage internal signals, an internal voltage divider is used. Figure 68. ADC MUX The diagnostics circuitry is activated by four SPI Diagnostics Control commands (DIAGCTRLx); each of them can address all the available nodes to be monitored, except for what mentioned in Table 18. DIAGCTRLx SPI command bit fields are structured in the following way: DIAGCTRL_A (ADDRESS HEX 3A) GAPG2104161155PS 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 MOSI x x x x x x x x x ADCREQ_A[6:0] MISO NEWDATA_A 0 0 ADCREQ_A[6:0] ADCRES_A[9:0] |
