Always write zeroes to this field.
Enables automatic DLL resyncs after every refresh.
Enables an automatic re-synchronization of the DLL after every refresh.
Always write zeroes to this field.
Initiate a DLL resync. WRITE-ONLY
Initiates a re-synchronization of the DLL. This parameter is write-only.
Always write zeroes to this field.
Limit concurrent auto-precharge by waiting for the write recovery time, tWR, before issuing a read.
Limit concurrent auto-precharge by waiting for the write recovery time, tWR, to complete after a write
before issuing a read.
'b0 = Do not restrict concurrent auto-precharge.
'b1 = Wait tWR after a write before issuing a read.
Always write zeroes to this field.
Register access to cke_status signal. This value also indicates the inverted state of the CKE pin on the
external memory bus. READ-ONLY
Provides the value of the cke_status signal in a parameter. This parameter is read-only.
