Synchronous burst read/write operation provides faster memory access that
synchronized to microcontroller or system bus frequency. Configuration Register
Set is required to perform burst read & write operation after power-up. Once CR
Set sequence is performed to select synchronous burst mode, the device is
configured to synchronous burst read/write operation mode with corresponding
RL and BL that is set through CR Set sequence together with operation mode. In
order to perform synchronous burst read & write operation, it is required to control
new signals, CLK, ADV# and WAIT# that Low Power SRAMs don’t have.
