Table 2-726 MSS_CTRL_PRU-ICSSSLAVE_BUS_SAFETY_ERR Register Field Descriptions

Bit	Field	Type	Reset	Description
31:24	PRU-ICSSSLAVE_BUS_SAFETY_ERR_DED	R	0h	This flag signals detection of dual error in Data at this port.Flag is generted for 32 bit segment of Data Bus Bit 0 - 1'b1 indicates ded on [31:0] bit of Data bus Bit 1 - 1'b1 indicates ded on [63:32] bit of Data bus Bit [7:2] - Unused. Set to 1'b0
23:16	PRU-ICSSSLAVE_BUS_SAFETY_ERR_SEC	R	0h	This flag signals detection of single error in Data at this port. Flag is generted for 32 bit segment of Data Bus Bit 0 - 1'b1 indicates sec on [31:0] bit of Data bus Bit 1 - 1'b1 indicates sec on [63:32] bit of Data bus Bit [7:2] - Unused. Set to 1'b0
15:8	PRU-ICSSSLAVE_BUS_SAFETY_ERR_COMP_CHECK	R	0h	This is used to verify the proper functioning of fault Injection on all the buses.1'b1 indicates error in the corresponding Bus has been injected successfully. Bit 0 - This is a Bitwise AND of error compares of all command bus signals. Bit 1 - This is a Bitwise AND of error compares of all write bus signals. Bit 2 - This is a Bitwise AND of error compares of all write status bus signals. Bit 3 - This is a Bitwise AND of error compares of all read bus signals. Bits [7:4] are unused.
7:0	PRU-ICSSSLAVE_BUS_SAFETY_ERR_COMP_ERR	R	0h	1'b1 indicates error in the corresponding Bus whenever a fault is detected at any bus signal Bit 0 - This is a Bitwise OR of error compares of all command bus signals. Bit 1 - This is a Bitwise OR of error compares of all write bus signals. Bit 2 - This is a Bitwise OR of error compares of all write status bus signals. Bit 3 - This is a Bitwise OR of error compares of all read bus signals. Bits [7:4] are unused.
