6 / 148 page Rev.1.01 Feb 15, 2008 Page 6 of 146 REJ03B0224-0101 455A Group Note 1. Pins except above have just single function. Note 2. The input/output of D5 can be used even when INT is selected. Be careful when using inputs of both INT and D5 since the input threshold value of INT pin is different from that of port D5. Note 3. “H“ output function of port C can be used even when the CNTR (output) is used.
