Note: 1) To protect the external power lines of peripheral devi ake sure that
- the wires have the right diameter to withstand the maximum available current.
- to enclosure of the peripheral device fulfills the fire-protecting conditions of IEC/EN 60950.

13.5 Special I/O Modes
13.5.1 IRQ Mode
All edge of the signal.
However for th lines are used. If
more IRQ pins shou the input pins.
13.5.2 Tri-Sta
tri-state mode the pins are automatically configured as output pins. In contrast to a standard ouput pin
the tri-state pin can also be used as an input pin (i.e. acknowledge from I2C-Bus).
sixteen I/O lines can be configured to trigger an interrupt on the falling or rising
e interrupt handling only IRQ6 and IRQ7 are available even when more
ld be used the identification of the source must be done by sampling
