Note: The following behavioral 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.

Port 2 is a 7-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 2 outputs can be configured as push/
pull or open drain drivers. The following Port 2 pins serve for
alternate functions:
EX1IN
Fast External Interrupt 1 Input
EX2IN
Fast External Interrupt 2 Input
EX3IN
Fast External Interrupt 3 Input
EX4IN
Fast External Interrupt 4 Input

Port 5 is a 2-bit input-only port with Schmitt-Trigger char. The
pins of Port 5 also serve as timer inputs:
