Termination of Initialization
The software initialization routine should be terminated with the EINIT instruction. This
instruction has been implemented as a protected instruction.
Execution of the EINIT instruction has the following effects:
• Disables the action of the DISWDT instruction,
• Disables write accesses to register SYSCON (all configurations regarding register
• Disables write accesses to registers SYSCON2 and SYSCON3
• Clears the reset source detection bits in register WDTCON,
• Causes the RSTOUT pin to go high
User’s Manual
SYSCON (enable CLKOUT, stacksize, etc.) must be selected before the execution of
EINIT),
(further write accesses to SYSCON2 and SYSCON3 can be executed only using a
special unlock mechanism),
(this signal can be used to indicate the end of the initialization routine and the proper
operation of the microcontroller to external hardware).
