| PDS51 pin problem |
|
I can't move pin P2.4 from its state.
At start time it's set to high level (1) and I can see it in PDS51 v3.44 watch pane.
But then I can't change its value to 0, neither by code nor by PDS51 watch pane (double click on watched variable).
If I apply an external voltage to the pin (0V or 5V) I can read it by the PDS51 watch pane.
I supposo it could be an internal emulator error.
Specs:
Philips PDS51 m.b. with PDB51Rx2 d.b.
Emulated device: Philiph 8xC52
