13 Multiple Error detection (ME) - This field is set to 1 when the New Error bit is set and one more
error is detected. Filtering is considered when setting the ME bit.
This field is only available in GR740 silicon revision 1.
12 Filter Write (FW) - This bit needs to be set to ‘1’ during a write operation for CF and AF fields to be
updated in the same write operation. Always reads as zero.
This field is only available in GR740 silicon revision 1.
11 Correctable Error Filter (CF) - If this bit is set to 1 then this status register will ignore correctable
errors. This field will only be written if the FW bit is set.
This field is only available in GR740 silicon revision 1.
10 AMBA ERROR Filter (AF) - If this bit is set to 1 then this status register will ignore AMBA
ERROR. This field will only be written if the FW bit is set.
This field is only available in GR740 silicon revision 1.
9 Correctable Error (CE) - Set if the detected error was caused by a correctable error and zero other-
wise.
8 New Error (NE) - Deasserted at start-up and after reset. Asserted when an error is detected. Reset by
writing a zero to it.
7 The HWRITE signal of the AHB transaction that caused the error.
6: 3 The HMASTER signal of the AHB transaction that caused the error.
2: 0 The HSIZE signal of the AHB transaction that caused the error
