1.1.3 Wiring for clock input/output pins
If noise enters clock I/O pins, clock waveforms may be deformed. This may cause a program failure or
program runaway. Also, if a potential difference is caused by the noise between the V
puter and the V
Connect the CNVss pin to the Vss pin with the shortest possible wiring.
The processor mode of a microcomputer is influenced by a potential at the CNVss pin. If a potential differ-
ence is caused by the noise between pins CNVss and Vss, the processor mode may become unstable. This
may cause a microcomputer malfunction or a program runaway.
