76 / 202 page  Page 66 5. I/O Ports TMP86CS64AFG Note 1: Don't set output mode to pin, which is used for an analog input. Note 2: When used for input mode (include analog input mode), read-modify-write instruction such as bit manipulate instructions cannot be used. Read-modify-write instruction writes the all data of 8-bit after data is read and modified. Because a bit setting input mode read data of terminal, the output latch is changed by these instructions. So P7 port cannot input data. Note: However the P7PU is set to “1” (pull-up), the port configured output is not set up pull-up resistor.
