Function
INT1
This pin is programmable as general input/output.
The state of the pin can be read from (input) / written
to (output) a register.
Additionally, as input it can generate a maskable
interrupt to the host, which is either edge or level
triggered. An internal pull up resistor is connected to
this pin (open drain mode only), if push pull
characteristic is selected no pull up is available.
As output an LED can directly be connected to this
pin.
SGO
Instead of the above described function, AUX7 can
also be programmed to output the S/G bit signal
from the IOM-2 DD line.

Crystal 1
Connection for a crystal or used as external clock
input. 7.68 MHz clock or crystal required.
Crystal 2
Connection for a crystal. Not connected if an
external clock is supplied to XTAL1.
Mode 0 Select
A LOW selects TE-mode and a HIGH selects LT-T /
