Notes:
1.
Sampled only, not 100% tested.
2.
Meaningful only if L is always kept Low.
3.
TWHEL and TWHLL have this value when reading in the targeted bank or when reading following a Set Configuration Register command.
System designers should take this timing into account and can insert a software No-Op instruction to delay the first read in the same bank after
issuing any command and to delay the first read to any address after issuing a Set Configuration Register command. If the first read after the
command is a Read Array operation in a different bank and no changes to the Configuration Register are issued, TWHEL and TWHLL are 0 ns.
