*: The external input channel which can be used is shown as follows.

• ch.0 to ch.3: MB9BF321M/F322M/F324M

• ch.0, ch.2, ch.3: MB9BF321K/F322K/F324K, MB9BF321L/F322L/F324L

Note:

−

All signals of the peripheral function in each product cannot be allocated by limiting the pins of package.

It is necessary to use the port relocate function of the I/O port according to your function use.
