Width-Expansion Configuration  
Flag Operation  
Word width may be increased simply by connecting the corre-  
sponding input controls signals of multiple devices. A  
composite flag should be created for each of the end-point  
status flags (EF and FF). The partial status flags (PAE and  
PAF) can be detected from any one device. Figure 2 demon-  
strates a 18-bit word width by using two CY7C42x1Vs. Any  
word width can be attained by adding additional CY7C42x1Vs.  
The CY7C4261/71/81/91V devices provide five flag pins to  
indicate the condition of the FIFO contents. Empty, Full, PAE,  
and PAF are synchronous.  
Full Flag  
The Full Flag (FF) will go LOW when the device is full. Write  
operations are inhibited whenever FF is LOW regardless of the  
state of WEN1 and WEN2/LD. FF is synchronized to WCLK,  
i.e., it is exclusively updated by each rising edge of WCLK.  
When the CY7C42x1V is in a Width-Expansion Configuration,  
the Read Enable (REN2) control input can be grounded (see  
Figure 2). In this configuration, the Write Enable 2/Load  
(WEN2/LD) pin is set to LOW at Reset so that the pin operates  
as a control to load and read the programmable flag offsets.  
Empty Flag  
The Empty Flag (EF) will go LOW when the device is empty.  
Read operations are inhibited whenever EF is LOW,  
regardless of the state of REN1 and REN2. EF is synchronized  
to RCLK, i.e., it is exclusively updated by each rising edge of  
RCLK.
