Hi,
on our RM46L852ZWT (BGA-package), we connected HET1-25 (Ball M3) to a 3,3V input signal. The input pin always provides a "0" and seems not to work as expected.
When we debug the program and configure this port to output (only change the bit 25 in the direction register), then we can measure High and Low signals corresponding to the DOUT register.
We even see the corresponding signal on the DIN register.
When we switch back to "input" than we just can see only a "0".
This behaviour seems to be on 5 different boards.
Need help. Maybe some special undocumented "please set bit 33 in the xyz register".
By the way:
The documentation of the N2HET registers in the Technical reference manual" is completely blank !!!!!!!!!!
Regards,
Markus
