Experiments
Use of the experiment push buttons and LEDs:
The K8048 is equipped with a max. of 4 test inputs that can be operated manually with
SW1,SW2,SW3 and SW4.
The device also has 6 diagnostics LEDs that enable the user to simulate outputs.
Click on the link "cross-reference table" to determine for every IC socket which I/O line is linked to
which push button or LED.

Remarks:
The I/O lines coming from a pushbutton have to be configured as inputs in the source
(a 1 in the TRIS-register
for that particular entrance). The I/O lines connected
with a LED must be configured as exits in the sources (a 0 in the TRIS-register for that
particular entrance).
