4.8.4 MUX_MC/BP_SEL

Signals PRG1_PWM (output from U29) and McASP10 (from Expansion Connector) are input to 2:1 mux U41. MUX_MC/BP_SE, control signal for mux U41 connects the input signals, either to Motor Control interface or to Booster pack interface. MUX_MC/BP_SE is set high or low by Jacinto7 EVM CP Board Configuration Switch SW3 position 8.
