Burst Type (MR0)
[Burst Length and Sequence]
Remark: T: Output driver for data and strobes are in high impedance.
V: A valid logic level (0 or 1), but respective buffer input ignores level on input pins.
X: Don’t Care.
Notes: 1. Page length is a function of I/O organization and column addressing
2. 0...7 bit number is value of CA [2:0] that causes this bit to be the first read during a burst.
