6.9.3.4 SOFTWARE WATCHDOG INTERRUPT VECTOR REGISTER (SWIV). The SWIV
contains the 8-bit vector that is returned by the SIM60 during an interrupt acknowledge cycle
in response to an interrupt generated by the SWT. This register can be read or written at any
time. This register is set to the uninitialized vector, $0F, at reset.
6.9.3.5 SYSTEM PROTECTION CONTROL REGISTER (SYPCR). The SYPCR controls
the system monitors, the prescaler for the SWT, and the bus monitor timing. This register
can be read at any time, but can be written only once after system reset.
MOTOROLA
1 = The last reset was caused by the software watchdog circuit.
1 = The last reset was caused by the double bus fault monitor.
1 = The last reset was caused by a loss of frequency reference to the clock sub-mod-
1 = The last reset was caused by the CPU32+ executing a RESET instruction. The RE-
1 = The last reset was caused by an external signal driving RESETS. See Section 3
ule. This reset can only occur if the RSTEN bit in the clock sub-module is set and
the VCO is enabled.
SET instruction does not load a reset vector or affect any internal CPU32+ regis-
ters or SIM60 configuration registers, but does reset external devices and other
internal modules. See Section 3 QUICC Memory Map for a listing of registers af-
fected by the hard reset. This bit is not valid in CPU disable mode.
