Idle State Cycle Between Read-Read
When read action is finish and next action is going to read, idle state is inserted and
nCS return to high if ExtIR2R is not zero.
Idle state cycle = (ExtIR2R*MCLK)
Reserved
Idle State Cycle After Write
When write action is finish, idle state is inserted and nCS return to high if ExtIW2X is
not zero.
Idle state cycle = (ExtIW2X*MCLK)
Reserved
EBI Data Access Hold Time
ExttAHD define data access hold time (tAHD).
tAHD = (ExttAHD +1) * MCLK
EBI Data Access Time
ExttACC define data access time (tACC).
tACC = (ExttACC +1) * MCLK
