1: Port input
Note 1: The port placed in input mode reads the pin input state. Therefore, when the input and output modes are used together,
the output latch contents for the port in input mode might be changed by executing a bit manipulation instruction.
Note 2: When used as an analog inport, be sure to clear the corresponding bit of P7CR2 to disable the port input.
Note 3: Do not set the output mode (P7CR1 = “1”) for the pin used as an analog input pin.
Note 4: Pins not used for analog input can be used as I/O ports. During AD conversion, output instructions should not be executed
to keep a precision. In addition, a variable signal should not be input to a port adjacent to the analog input during AD con-
version.
