Discharge Check

Active discharge is enabled by default and not NVM based. Thus, if desired, it need to be disabled after each VSYS-power-cycle. During RESET or OFF-request, the discharge configuration is not reset, as long as VSYS is present. However, in INITIALIZE state and prior to the power-up-sequence, all rails are discharged, regardless of the setting. In case active discharge on a rail is disabled, it does not gate the disable of the subsequent rail, but the sequence is purely timing based. In case of residual voltage, the RV-bit is be set regardless.
