System Integration Module (SIM60)
Bus Monitor
On the MC68302, this function is called the hardware watchdog.
Double Bus Fault Monitor
6-4
The SIM60 provides a bus monitor to monitor the data and size acknowledge (DSACK)
response time for all bus accesses (internal-to-internal, internal-to-external, external-to-
internal, and external-to-external). Four selectable response times allow for variations in
response speed of memory and peripherals used in the system. A bus error signal is as-
serted if the DSACK response limit is exceeded. This function can be disabled.
The double bus fault monitor causes a reset to occur if the internal HALT signal is assert-
ed by the CPU32+, indicating a double bus fault. A double bus fault results when a bus or
address error occurs during the exception processing sequence for a previous bus or ad-
dress error, a reset, or while the CPU32+ is loading information from a bus error stack
frame during an RTE instruction. This function can be disabled. See Section 4 Bus Oper-
ation for more information.
