Description
EINIT
End of Initialization
This instruction is used to signal the end of the initialization portion of a
program. 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 program to signal the external circuitry that it
has successfully initialized the microcontroller. After the EINIT instruction
has been executed, execution of the Disable Watchdog Timer instruction
(DISWDT) has no effect. To insure that this instruction is not accidentally
executed, it is implemented as a protected instruction.
