Note: The following behavioural 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 as if it were a hardware reset. In particular, 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.
