Self refresh entry command
(/CS, /RAS, /CAS, CKE = Low, /WE = High)
After the command execution, self refresh operation continues while
CKE remains low. When CKE goes high, the
μ
PD45128xxx exits the
self refresh mode.
During self refresh mode, refresh interval and refresh operation are
performed internally, so there is no need for external control.
Before executing self refresh, all banks must be precharged.
