mcf5272的引脚比较多，设计原理图的时候比较复杂，可以用该的规范原理图，protel99se格式。-MCF5272 more of the pin, when the schematic design more complicated, can be used in the schematic diagram of the specification, protel99se format.

将单片机的IOA0~IOA7分别接按键S1~S8连接到高电平上。此时，如果某个按键被按下，对应的I/O端口就会输入高电平进单片机，即按键S3按下，IOA2会输入高电平进单片机-Will Singlechip IOA0 ~ IOA7 access keys, respectively, S1 ~ S8 is connected to high on. At this point, if a button is pressed, the corresponding I/O port will enter into the high single-chip, that is, S3 button press, IOA2 will enter into single-chip high
