It is useful for obtaining the status of the output during normal operation The value of this bit depends on the channel configuration: 0: Drain voltage low (VDRAIN < VLVT) -> transistor ON 1: Drain voltage high (VDRAIN > VLVT) -> transistor OFF (Low-Side with NFET) 0: Drain voltage low (VDRAIN < VOL) -> transistor OFF 1: Drain voltage high (VDRAIN > VOL) -> transistor ON (High-Side with NFET/PFET) Reset: 1111 Reset Condition: POR, NRES [16:13] C4…1: This bit combines the control signals SPI_ON_OUTxx, NONx and SPI_input_sel_xx to determine if the x-th channel is commanded ON or OFF 0: output commanded OFF 1: output commanded ON Reset: 0000 Reset Condition: POR, NRES L9945 Functional description DS12275 - Rev 10 page 103/144 |
