Cautions
1. Codes marked by brackets refer to processing by pins unused in PROM programming mode.
L
: Connect to VSS individually via a resistor.
G
: Connect to VSS.
Open : Do not connect anything.
2. As a measure against noise, please connect the NC pin to VSS. (It is also possible to leave this pin
unconnected.)
