Many secure applications have requirements to disable error notifications to the outside world. These applications want to disable the PS_ERROR_OUT and PS_ERROR_STATUS signals. The registers that control these signals are described in Table: Global Registers in Platform Management Unit. The user software must be loaded and executing to control these registers.

The ERR_DIS eFUSE permanently disables reading of the PS_ERROR_STATUS register from the external JTAG chain.
