Function
−
The 78K0S/KU1+ 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.
The constants described in the circuit connection example are reference values. If
you perform flash programming aiming at mass production, thoroughly evaluate
whether the specifications of the target device are satisfied.
If debugging is performed with a real machine running, without using QB-MINI2,
write the user program using the QB-Programmer. Programs downloaded by the
debugger include the monitor program, and such a program malfunctions if it is
not controlled via QB-MINI2.
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.
When using the X1 oscillator, wire as follows in the area enclosed by the broken
lines in the above figures to avoid an adverse effect from wiring capacitance.
• Keep the wiring length as short as possible.
• Do not cross the wiring with the other signal lines.
• Do not route the wiring near a signal line through which a high fluctuating
• Always make the ground point of the oscillator capacitor the same potential as
• Do not ground the capacitor to a ground pattern through which a high current
• Do not fetch signals from the oscillator.
The conversion accuracy may be degraded if the level of a port that is not used
for A/D conversion is changed during A/D conversion.
For soldering methods and conditions other than those recommended below,
contact an NEC Electronics sales representative.
Do not use different soldering methods together (except for partial heating).
