usb0

This register is used to enable ECC on the USB0 RAM. ECC errors can be injected into the write path using bits in this register. This register contains interrupt status of the ECC single/double bit error. Only reset by a cold reset (ignores warm reset).

This bit is an interrupt status bit for USB0 RAM ECC double bit, non-correctable error. It is set by hardware when double bit, non-correctable error occurs in USB0 RAM. Software needs to write 1 into this bit to clear the interrupt status.

This bit is an interrupt status bit for USB0 RAM ECC single, correctable error. It is set by hardware when single, correctable error occurs in USB0 RAM. Software needs to write 1 into this bit to clear the interrupt status.
