Data Sheet  
FS6377-01/FS6377-01g Programmable 3-PLL Clock Generator IC  
5.1.2 START Data Transfer  
A high to low transition of the SDA line while the SCL input  
is high indicates a START condition. All commands to the  
device must be preceded by a START condition.  
5.1.3 STOP Data Transfer  
A low to high transition of the SDA line while SCL is held  
high indicates a STOP condition. All commands to the  
device must be followed by a STOP condition.  
5.1.4 Data Valid  
The state of the SDA line represents valid data if the SDA  
line is stable for the duration of the high period of the SCL  
line after a START condition occurs. The data on the SDA  
line must be changed only during the low period of the  
SCL signal. There is one clock pulse per data bit.  
terminated with a STOP condition. The number of data  
bytes transferred between START and STOP conditions is  
determined by the master device, and can continue  
indefinitely. However, data that is overwritten to the device  
after the first sixteen bytes will overflow into the first  
register, then the second, and so on, in a first-in, first-  
overwritten fashion.  
Each data transfer is initiated by a START condition and  
5.1.5 Acknowledge  
When addressed, the receiving device is required to  
generate an acknowledge after each byte is received. The  
master device must generate an extra clock pulse to  
coincide with the acknowledge bit. The acknowledging  
device must pull the SDA line low during the high period of  
the master acknowledge clock pulse. Setup and hold  
times must be taken into account.  
The master must signal an end of data to the slave by not  
generating an acknowledge bit on the last byte that has  
been read (clocked) out of the slave. In this case, the  
slave must leave the SDA line high to enable the master  
to generate a STOP condition.  
5.2 I2C-bus Operation  
All programmable registers can be accessed randomly or  
sequentially via this bi-directional two wire digital interface.  
The device accepts the following I2C-bus commands.  
5.2.1 Slave Address  
After generating a START condition, the bus master  
broadcasts a seven-bit slave address followed by a R/W  
bit. The address of the device is:  
where X is controlled by the logic level at the ADDR pin.  
The variable ADDR bit allows two different devices to exist  
on the same bus. Note that every device on an I2C-bus  
must have a unique address to avoid bus conflicts. The  
default address sets A2 to one via the pull-up on the ADDR  
pin.

5.2.2 Random Register Write Procedure  
Random write operations allow the master to directly write  
to any register. To initiate a write procedure, the R/W bit  
that is transmitted after the seven-bit device address is a  
logic-low. This indicates to the addressed slave device that  
a register address will follow after the slave device  
acknowledges its device address. The register address is  
written into the slave's address pointer. Following an  
acknowledge by the slave, the master is allowed to write
