3.3.2.1 SCbus Error Status Register
The SCbus Status Register stores the bus error detect enable bit, BEDE,
and the bus error detected bit, BERR. The register’s virtual address is
0xB010 0004 and its physical address is 0x1010 0004. For further
information about this register, refer to
“SCbus Timeout Watchdog Timer”
on page 7-8

BEDE
Bus Error Detect Enable
When this bit is set to 1, the LR4500 is enabled to detect
SCbus errors.

3.3.2.2 SCbus Error Address Register
The SCbus Error Address Register stores the address of the transaction
that has caused the bus error. The address remains stored during the
period that the bus error bit, BERR, is set. The register’s virtual address
is 0xB010 0000 and its physical address is 0x1010 0000. For further
information about this register, refer to
