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.
RST PRG INx MUXx SCONx Output OUTx of Power Stage x, x = 1..6
0 X X X X OUTx off
1 X X 0 0 Serial Control: OUTx on
1 X X 0 1 Serial Control: OUTx off
1 0 0 1 X Parallel Control: OUTx on
1 0 1 1 X Parallel Control: OUTx off
1 1 0 1 X Parallel Control: OUTx off
1 1 1 1 X Parallel Control: OUTx on
Note: Serial Data bits are low active. Parallel Inputs are high or low active depending on the PRG pin.
