Data Output – DQ[3:0] – – DQ[3:0] DQ[3:0]
Notes:
1. Yes in the "Supported" row for each protocol indicates that the command in that col-
umn is supported; when supported, a command's functionality is identical for the entire
column regardless of the protocol. For example, a FAST READ functions the same for all
three protocols even though its data is input/output differently depending on the pro-
tocol.
2. FAST READ is similar to READ, but requires dummy clock cycles following the address
bytes and can operate at a higher frequency (
f
C).
