2 Clock generating circuit  
The 38C3 group is the 8-bit microcomputer based on the 740 family  
core technology.  
The 38C3 group has a LCD drive control circuit, a 10-channel A-D  
converter, and a Serial I/O as additional functions.  
The various microcomputers in the 38C3 group include variations of  
internal memory size and packaging. For details, refer to the section  
on part numbering.
