The following are the parameters for enabling or disabling the

Watchdog Timer function when using the GWBASIC or

ASSEMBLY applications.

When enabled, the application accesses read port 443 (HEX).

When disabled, it accesses read port 43 (HEX).

GWBASIC

To enable Watchdog Timer and reload the timer, type:

A = INP (&H443)

To disable, type:

A = INP (&H43)

ASSEMBLY

To enable Watchdog Timer and reload the timer, type:

MOV

DX, 0443H

AL, DX

To disable, type:

MOV

DX, 043H

AL, DX

Please note that your custom software must regularly reload the
