Description
After a reset, the reset output pin RSTOUT is pulled low. It remains low until the EINIT
instruction has been executed at which time it goes high. This enables the software to
signal the external circuitry that it has successfully initialized the microcontroller. After
EINIT execution, registers can be locked until reset. The DISWDT instruction executed
after the first EINIT instruction has effect only if the WDTCTL bit was cleared before the
EINIT instruction. To ensure that this instruction is not accidentally executed, it is
implemented as a protected instruction.
