The cycle is also avaiilable for initialization cycle, but in this case device enters test mode.
The test mode function is initiated with a W and CAS before RAS cycle(WCBR cycle) as specified above timing diagram.
The test mode function is terminated by either a CAS before RAS(CBR) refresh or a RAS only refresh cycle.
During the test mode, the device is internally organized as 4-bits wide (256-kilobytes deep) for each DQ (input/output) port.
No addressing of A

(column only) is required.
During a write cycle, data on the each DQ (input) pin is written in parallel into all 4-bits for each DQ port and can be written independently
for each DQ port.
During a read cycle, the each DQ (output) pin indicates independently a HIGH state if all 4-bits are equal, and a LOW state if any bits
differ.
During the test mode operation, a WCBR cycle is used to perform refresh.
