NOTES:
1. ROM size depends on microcomputer type.
2. RAM size depends on microcomputer type.
3. Ports P11 to P14 exist only in 128-pin version.
4. Use M16C/62PT on VCC1=VCC2.
# All voltages are measured with a 10MΩ/V DC electronic volt meter.
# Components having special characteristics are marked s and must be replaced
with parts having specifications equal to those originally installed.
