Function
Address Bus, demultiplexed bus mode.
Transfers addresses from the P-system to the
ELIC.
Port 0, multiplexed bus mode.
Parallel input port. The current data is latched with
the falling edge of RD, DS.
Port 1
4-bit I/O port. Every pin can be configured
individually as input or output. For inputs the
current data is latched with the falling edge of RD,
DS.
Interrupt Request, active low.
This signal is activated when the ELIC requests an
interrupt. Due to the open drain (OD)
characteristic of INT multiple interrupt sources can
be connected together.
Reset Indication
This pin is set to "high", when the ELIC executes
either a power-up reset, a watchdog timer reset,
an external reset (RESEX) or a software system
reset.
Reset External
A "high" forces the ELIC into reset state.
