Read Status (Idle) Mode  
The Read Status Mode uses the CSI host interface to disconnect the flash memory array from the DOUT  
bus and makes the CSI status register available for subsequent host read cycles (Figure 8.3). Assuming  
all program operations are complete, the CSI flash interface sets the Flash Memory Array interface  
signals to the standby mode for the duration of the Read Status mode. The CSI host interface and the  
Flash Memory Array remain in the Read Status (Idle) mode indefinitely until the next command is given.  
In Read Status mode, write cycles to the 64k Embedded Flash Host Interface program the CSI  
command register (not shown in Figure 8.3).  
8.3.7.7  
Clear Status Mode  
The Clear Status Mode uses the CSI host interface to disconnect the flash memory array from the DOUT  
bus, deasserts the status register error bits (Table 8.8), and makes the CSI status register available for  
subsequent host read cycles (Figure 8.3). The CSI flash interface sets the Flash Memory Array signals  
to the standby mode for the duration of the Clear Status mode. The CSI host interface and the Flash  
Memory Array interface remain in the Read Status (Idle) mode until the next command is given.
