REGSCPEN 23 R/W RESETB 0
Register short-circuit protect enable. This bit should be set to 1 to
reduce power dissipation on the external pass LDOs (VUSB2, VGEN2,
and VDAC). When a short-circuit condition is detected, the LDO’s
VxEN bit is set to 0, disabling the LDO and an SCPI interrupt will be
generated
