2. Electrical Characteristics

Note 1.

Programming or erasing the flash memory is disabled in Subosc-speed mode.

Note 2.

See section 9, Clock Generation Circuit in Userʼs Manual for the relationship between the ICLK, PCLKA, PCLKB, PCLKC,

PCLKD, FCLK, and BCLK frequencies.

Note 3.

The ADC12 cannot be used.
