The DIR,
register contains the same value as the JTAG IDCODE register. The version number field will change if a
new revision of the MCF5272 is created.

6.2.8
The software watchdog timer prevents system lockup should the software become trapped in loops with
no controlled exit. The software watchdog timer can be enabled or disabled through WRRR[EN]. If
enabled, the watchdog timer requires the periodic execution of a software watchdog servicing sequence.
If this periodic servicing action does not occur, the timer counts until it reaches the reset timeout value,
resulting in a hardware reset with RSTO driven low for 16 clocks. SCR[RSTSRC] is updated to indicate
that the software watchdog caused the reset.
