ROGRAMMING
The S1C8F360 Adapter Board (S5U1C8F360Z1) connected to the On Board Programming Writer
(S5U1C88000W3) allows writing user data to the Flash EEPROM built into the S1C8F360/8F361 (package
model) placed on its IC socket using the On Board Programming Writer Control Software
(S5U1C8F360Y3).
Refer to "Appendix PROM programming" in the "S1C8F360 Technical Manual" for the programming
procedure.
5.1 Setting the Jumpers
Before performing serial programming, set the jumpers for the power unit as shown in Table 5.1.1.
Note: Be aware that the configuration is different between the S1C8F360 and the S1C8F361.
