PROBLEM WITH I/O PORT 2...."BUG" ??
I have the following 2 port lines in use as follows:
P2.1 = OUTput sending a TTL signal level to an external part of the circuit (BIS.B #BIT1,&P2DIR)
P2.2 = Analog input. (BIC.B #BIT2, &P2DIR)+ ADC allowable input set to include A2 (=P2.2)
THE PROBLEM. When I set P2.1 to 'output'.... P2.2 is turned into a short, and my analog voltage disappears.
ERRATA I could not find any reference to this situation in the Errata file for the device.
My Schematic is attached.
