1.6 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.
