Function
When write enable input WEB is set to "L", the contents of data inputs D0 to D7 are read in synchronization with a
rising edge of write clock input WCK to perform writing operation. When this is the case, the write address counter is
also incremented simultaneously.
When WEB is set to "H", the writing operation is inhibited and the write address counter stops.
When write reset input WRESB is set to "L", the write address counter is initialized.
When read enable input REB is set to "L", the contents of memory are output to data outputs Q0 to Q7 in
synchronization with a rising edge of read clock input RCK to perform reading operation. When this is the case, the
read address counter is incremented simultaneously.
When REB is set to "H", the reading operation is inhibited and the read address counter stops. The outputs are placed
in a high impedance state.
When read reset input RRESB is set to "L", the read address counter is initialized.
