Indeed! Thank you Jan, this is something i can work with. I had this port connected to gnd.

(See Philips datasheet TSA5514, table 4).
It's about the MA0 and MA1 bits (Master Address Select).
Question; what to apply now in such a manner that the commands from the 16F627A controller are accepted by the TSA5514?
I'am really a n00b here... :-((
The applied voltage can vary between 0 (GND) and 1 (VCC, 5V).
(table 4)
MA1 MA0 VOLTAGE APPLIED ON PIN AS
0 0 0 to 0.1 Vcc
0 1 open
1 0 0.4 to 0.6 Vcc
1 1 0.9 Vcc to Vcc
Can you give me a hint?
Kind regards,
Harm
