Accessing Mode Register: Starts with registration of a MODE REGISTER SET command and ends when tMRD has been
met.
Once tMRD is met, the LPDDR will be in an all banks idle state.
Precharging All: Starts with the registration of a PRECHARGE ALL command and ends when tRP is met. Once tRP is met,
the bank will be in the idle state.
10.
Not bank-specific; requires that all banks are idle and no bursts are in progress.
11.
Not bank-specific. BURST TERMINATE affects the most recent READ burst, regardless of bank.
12.
Requires appropriate DM masking.
13.
A WRITE command may be applied after the completion of the READ burst; otherwise, a BURST TERMINATE must be
used to end the READ prior to asserting a WRITE command.
