CHAPTER 25 ON-CHIP DEBUG FUNCTION
25.1 Connecting QB-78K0MINI to 78K0/LC3
The 78K0/LC3 uses the VDD, FLMD0, RESET, OCD0A/X1, OCD0B/X2, and VSS pins to communicate with the host
machine via an on-chip debug emulator (QB-78K0MINI).
Caution
The 78K0/LC3 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 after the on-chip debug function has been used.
