Microprocessor( Cpu) Control Circuit - FSP Technology EP 1000 Series Specification

8 Microprocessor( CPU) Control Circuit

The CPU is supplied by + 5Vdc power supply to pin7 with ground pin at pin3. An
extra oscillation circuitry consisting of C01, C02, and crystal XL1 is connected to pin4 &5.
The Vesta series is using MOTOROLA/ MC68HC908JL8CSP CPU. The pin definition is listed
