Serial/Parallel Control of the Power Stages 1...6
(SPI-Instructions: WR_MUX, RD_MUX, WR_SCON, RD_SCON)
The following table shows the truth table for the control of the power stages 1...6. The register
MUX_REG prescribes parallel or serial control of the power stages. The register SCON_REG
prescribes the state of the power stage in case of serial control.
