It's Note
Supply power evaluation board attached power cord. (Red wire +5V, Black GND, Brown +3V.) shown circuit diagram, power supply peripherals, power supply D.U.T. Switches Terminals used open/close MSM7582 signals such PDN0, PDN1, PDN2, SLS1, SLS2, RCW, AFC, corresponding switches). With terminals closed, signal asserted negated control switches With terminals open, control signals input directly through pins monitor these puts, HC4050 buffers provided with that both drive capable. Terminals used open/close serial control register input MSM7582. MSM7582 mode through closed terminal peripherals board. With terminals open, control signals input directly through pins monitor serial control register input pins (DEN, EXCK, DIN). Terminal used control input MSM7582. this terminal follows, depending whether oscillating circuit MSM7582 used.
