I/O
Port 5
Port 5 serves as 16-bit general purpose I/O port, 3 pins
of which (P5.0, P5.2 and P5.15) serve as output lines
for MultiMediaCard Interface (MMCI) also.

A1 I/O  Hardware Reset Input/Reset Indication Output
Assertion of this bidirectional open-drain pin causes a
synchronous reset of the chip through external
circuitry. This pin must be driven for a minimum
duration.
The internal reset circuitry drives this pin in response
to a power-on, hardware, watchdog, power-down
wake-up reset and eDRAM reset for a specific period
of time. For a software reset, activation of this pin is
programmable.
C3 I PUC Power-on Reset Input
A low level on PORST causes an asynchronous reset
of the entire chip. PORST is a fully asynchronous level
sensitive signal.
