6.2.6 Software Watchdog Interrupt Vector Register (SWIVR)
The SWIVR, shown in Figure 6-6, contains the 8-bit interrupt vector (SWIV) that the SIM
returns during an interrupt-acknowledge cycle in response to a software watchdog
timer-generated interrupt. SWIVR is set to the uninitialized vector 0x0F at system reset.
Note that the software watchdog interrupt cannot be autovectored.
6.2.7 Software Watchdog Service Register (SWSR)
The SWSR, shown in Figure 6-7, is where the software watchdog timer servicing sequence
should be written. To prevent a watchdog timer timeout, the software service sequence must
be performed (0x55 followed by 0xAA written to the SWSR). Both writes must be
performed in order before the timeout, but any number of instructions or accesses to the
SWSR can be executed between the two writes. If the timer has timed out, writing to SWSR
does not cancel the interrupt (that is, IPR[SWT] remains set). The interrupt is cancelled
(and SWT is cleared) automatically when the IACK cycle is run.
