after reset. While the port is in input mode, voltage level on the pins is indeterminate and power consumption
may increase. Direction register setting may be changed by noise or failure caused by noise. Configure
direction register settings regulary to increase the reliability of the program.
85-pin packages, set bits PACR2, PACR1, and PACR0 to 011
