• Burst Read Termination
Burst read operation can be terminated by CE1 brought to High. If BL is set on Continuous, the burst read
operation is continued endlessly unless terminated by CE1 = H. It is inhibited to terminate the burst read before
first data output is completed. In order to guarantee last data output, the specified minimum value of CE1 = L
hold time from the clock edge must be satisfied. After termination, the specified minimum recovery time is required
to start a new access.

• Burst Write Termination
Burst write operation can be terminated by CE1 brought to High. If BL is set on Continuous, the burst write
operation is continued endlessly unless terminated by CE1 = H. It is inhibited to terminate the burst write before
first data input is completed. In order to guarantee last data input being latched, the specified minimum values
of CE1 = L hold time from the clock edge must be satisfied. After termination, the specified minimum recovery
time is required to start a new access.
