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.

Port 8 is a 4-bit bidirectional I/O port. It is bit-wise
programmable for input or output via direction bits. For a pin
configured as input, the output driver is put into high-
impedance state. Port 8 outputs can be configured as push/
pull or open drain drivers. The input threshold of Port 8 is
selectable (TTL or special). Port 8 pins provide inputs/
outputs for CAPCOM2 and serial interface lines.1)
