In addition to the basic watchdog timer included in the 80515 MPU, an
independent, robust, fixed-duration, watchdog timer (WDT) is included in
the device. It uses the crystal oscillator as its time base and must be
refreshed by the MPU firmware at least every 1.5 seconds. When not
refreshed on time the WDT overflows, and the part is reset as if the
RESET pin were pulled high, except that the I/O RAM bits will be
maintained. 4096 oscillator cycles (or 125 ms) after the WDT overflow,
the MPU will be launched from program address 0x0000. Asserting
ICR_E will deactivate the WDT.
The WDT can also be disabled by tying the V1 pin to V3P3. Of course,
this also deactivates V1 power fault detection. Since there is no method
in firmware to disable the crystal oscillator or the WDT, it is guaranteed
that whatever state the part might find itself in, upon WDT overflow, the
part will be reset to a known state.

1.5.11 Test Ports (TXUXOUT pin)
One out of 16 digital or 8 analog signals can be selected to be output on the TMUXOUT pin. The
function of the multiplexer is described in the applicable firmware documentation.
