System Integration Module (SIM60)
master may generate a bus error as a result of this register, and for parity errors, the PERR
pin may be externally connected to an interrupt input.
Bits 15–9—Reserved
WPER—Write Protect Error
PERx—Parity Error
6.13.3 Base Register (BR)
This register is used for both DRAM and SRAM banks. Most bits are valid for both the DRAM
and SRAM banks, but some bits are only valid for SRAM banks. This register is a 32-bit
read-write register that may be accessed at any time.

This bit is asserted when a write protect error occurs. A bus monitor (BERR assertion) will
(if enabled) prompt the user to read this register if no DSACK is provided on a write cycle.
The accessed address will be in the BERR exception descriptor. WPER is cleared by writ-
ing one to this bit or by performing a system reset. Writing a zero has no effect on WPER.
These bits indicate that a parity error was detected when reading from bank N. BERR is
internally asserted if PBEE in the GMR is set and if an internal master performs this cycle.
The PERR signal is continuously asserted until all PERx bits are cleared. PERx is cleared
by writing one or by performing a system reset. Writing a zero has no effect on PERx.
This bit indicates that the contents of the BR and OR pair are valid. The CS/RAS signal
will not assert until the V-bit is set.

If external masters of the MC68030-type (including QUICCs) are
chosen to be asynchronous (configured by clearing the SYNC
bit in the GMR), then they have no parity support.
