Outline of Functions

[30-pin, 32-pin, 36-pin, 40-pin products (code flash memory 16 KB to 64 KB)]

Caution

This outline describes the functions at the time when Peripheral I/O redirection register 0, 1

(PIOR0, 1) are set to 00H.

(1/2)

Note

In the case of the 5.5 KB, this is about 4.5 KB when the self-programming function and data flash function are used.
