The MODE pinstrap configuration programs the control topology and internal soft-start timing selections. The TPS549B22 device supports both D-CAP3 control mode and DCAP operation
MODE[4] selection bit is used to set the control topology. If MODE[4] bit is 0, it selects DCAP operation. If MODE[4] bit is 1, it selects D-CAP3 control mode operation.
MODE[1] and MODE[0] selection bits are used to set the internal soft-start timing.
