errors do not raise exceptions or cause the DMA engines to stop, so the Bus Watcher interrupt is likely to be
the only way they are reported.
READ ONLY, Read will clear all fields and the cor_ecc_int and bad_ecc_int interrupts

Table 35: Bus Watcher Error Status Register

bus_err_status - 00_1002_0880
Default
8'b0 Reserved
10'b0 Transfer ID that had error code. Top 4 bits indicate the initiator of the
transfer, see
more details on the what within the agent caused the transaction, see
Table 51 on page
4'b0 Responder ID identifies the agent that reported the error. See
Table 1 on page
3'b0 Data transfer error code. See
5'b0 Reserved
1'b0 Set to indicate multiple errors. The first fatal one, or the most recent non-
fatal one is logged (all were counted).
1'b1 Reserved. Reads as 1.
32'bx Not Implemented.

Table 36: Bus Watcher Error Status Debug Register

bus_err_status_debug - 00_1002_08D0 READ ONLY
Default
64'hx This register contains the same information as the bus_err_status
register, but reads do not have any side effects.
