Note: The following behaviour differences must be observed when the bidirectional reset
is active:
• Bit BDRSTEN in register SYSCON cannot be changed after EINIT and is cleared
automatically after a reset.
• The reset indication flags always indicate a long hardware reset.
• The PORT0 configuration is treated like on a hardware reset. Especially the bootstrap
loader may be activated when P0L.4 is low.
• Pin RSTIN
may only be connected to external reset devices with an open drain output
driver.
• A short hardware reset is extended to the duration of the internal reset sequence.
