Caution
The
μPD78F0397D has an on-chip debug function. Do not use this product for mass production
because its reliability cannot be guaranteed after the on-chip debug function has been used,
given the issue of the number of times the flash memory can be rewritten. NEC Electronics does
not accept complaints concerning this product.

Caution
Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any
parameter. That is, the absolute maximum ratings are rated values at which the product is on the
verge of suffering physical damage, and therefore the product must be used under conditions that
ensure that the absolute maximum ratings are not exceeded.
Remark
Unless specified otherwise, the characteristics of alternate-function pins are the same as those of port pins.
