The Second Command (The next clock of RDA or WRA command)
Notes :
1. L = Logic Low, H = Logic High, X = either L or H, V = Valid (Specified Value), BA = Bank Address, UA = Upper Address,
LA = Lower Address.
2. All commands are assumed to issue at a valid state.
3. All inputs for command (excluding SELFX and PDEX) are latched on the crossing point of differential clock input where
CLK goes to High.
4. Operation mode is decided by the comination of 1st command and 2nd command refer to "STATE DIAGRAM" and the
