VRC_CTRL Voltage Regulator external
BYPASS
Reset configuration is given as I/O direction and pull direction (for example, “Input, pullup”).
Although this signal is not a supply for RSDS pads, it needs to be terminated in an external capacitor with a value of 47 pF.
VREG_BYPASS should be connected to ground during normal operation.
