68 / 272 page  Page 56 5. I/O Ports 5.2 Port P1 (P10 to P17) TMP86FS28DFG Figure 5-3 Port P1 Note 1: Pins set to input mode read the pin input data. Therefore, when both input and output modes are used in Port P1, the contents of the output latch of a pin set to input mode may be overwritten by a bit manipulation instruction. Note 2: For a pin used as an analog input, be sure to clear the corresponding bit in P1CR2 to "0" to prevent flow-through current. Note 3: For a pin used as an analog input, do not set P1CR1 to "1" (port output) to prevent the pin from becoming shorted with an external signal. Note 4: Pins not used as analog inputs can be used as input/output pins. During AD conversion, however, output instruc- tions must not be executed to ensure the accuracy of conversion results. Also, during AD conversion, do not input signals that fluctuate widely to pins near analog input pins.
