Notes:
1 = driven to VCC
0 = driven to VSS
X = driven to unknown state
ID = The input is disabled.
H = pulled up to VCC
PD = pull-up disabled
L = pulled down to VSS
ODT = On Die Termination
GND = Tie to Ground.
EA = External Arbiter mode
IA = Internal Arbiter mode
Z = output, pull-up/down disabled
VB = acts like a Valid Bidirectional pin
VO = a Valid Output level is driven.
VI = need to drive a Valid Input level.
AO = Analog Output level
AI = Analog Input level
* = after power fail sequence completes
“-” = unaffected by this mode
a. MA[14] is only needed for 4GB memory support. When 4GB memory is not used this pin is NC.
