CKEn is the logic state of CKE at clock edge n; CKEn-1 was the state of CKE at the previous clock edge.
Current state is the state of LPDDR immediately prior to clock edge n.
COMMANDn is the command registered at clock edge n, and ACTIONn is the result of COMMANDn.
All states and sequences not shown are illegal or reserved.
DESELECT and NOP are functionally interchangeable.
Power Down exit time (tXP) should elapse before a command other than NOP or DESELECT is issued.
SELF REFRESH exit time (tXSR) should elapse before a command other than NOP or DESELECT is issued.
The Deep Power-Down exit procedure must be followed as discussed in the Deep Power-Down section of the Functional
Description.
The clock must toggle at least once during the tXP period.
The clock must toggle at least once during the tXSR time.
