APPROVED PRODUCT  
C9811x2  
Low EMI Clock Generator for Intel 810 Chipset Systems  
Serial Control Registers  
NOTE: The Pin# column lists the affected pin number where applicable. The @Pup column gives the state at true  
power up. Bytes are set to the values shown only on true power up.  
Following the acknowledge of the Address Byte, two additional bytes must be sent:  
1) Command Code byte, and  
2) Byte Countbyte.  
Although the data (bits) in these two bytes are considered dont care; they must be sent and will be acknowledged.  
After the Command Code and the Count bytes have been acknowledged, the sequence described below (Byte 0, Byte 1,  
and Byte2) will be valid and acknowledged.  
Byte 0: CPU Clock Register (1=Enable, 0=Disable, Default=07)  
Byte 1: SDRAM Clock Register (1=Enable, 0=Disable, Default=FF)
