Cautions
The 78K0R/KH3 has an on-chip debug function, which is provided for development and
evaluation.
Do not use the on-chip debug function in products designated for mass
production, because the guaranteed number of rewritable times of the flash memory may be
exceeded when this function is used, and product reliability therefore cannot be guaranteed.
NEC Electronics is not liable for problems occurring when the on-chip debug function is
used.

Notes 1. Must be 6.5 V or lower.
2. Connect the REGC pin to Vss via a capacitor (0.47 to 1
μF). This value regulates the absolute
maximum rating of the REGC pin. Do not use this pin with voltage applied to it.
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.
