Operation
Disable the watchdog timer
Description
This instruction disables the Watchdog Timer. If the WDTCTL bit is cleared, the
DISWDT instruction can be executed at any time between the Reset and the first
execution of either EINIT or SRVWDT. After execution of either an EINIT or a
SRVWDT, the DISWDT instruction will have no effect. If the WDTCTL bit is set, the
DISWDT instruction can always be executed regardless of the execution of EINIT or
SRVWDT. To ensure that this instruction is not accidentally executed, it is implemented
as a protected instruction.
