Notes:
1. Sampled only, not 100% tested.
2.
T
has this value when reading in the targeted bank or when reading following a Set Configuration Register command. System designers
WHEL
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, T
is 0 ns.
