Clock Suspend
The Clock Suspend command is used to suspend the internal clock of Mobile SDRAM. The clock suspend operation
stops transmission of the clock to the internal circuits of the device during burst transfer of data to stop the operation
of the device. During normal access mode, CKE is keeping High. When CKE is low, it freezes the internal clock and ex-
tends data Read and Write operations. (See examples in next Figures)
