1) Detection is enabled via SDCON register in active mode. It is automatically disabled in power down mode.
Detection should be disabled for VDDP less than maximum of VDDPPW
.
2) This parameter has a hysteresis of 50 mV.
3) Detection is enabled via SDCON register. Detection must be disabled for application with V
