Wait State Control: As the clock frequency increases, it becomes impossible to complete all
states in one cycle as in basic access. Therefore, provision is made for state extension by using the
setting bits in WCR2 and MCR. The timing with state extension using these settings is shown in
figure 10.35. Additional Tpc cycles (cycles used to secure the CE precharge time) can be inserted
by means of the TPC bits in MCR. The number of OE and WEn assert cycles from RAS assertion
to CAS assertion can be varied between 1 and 3 according to the setting of A3W1 and A3W0 in
WCR2. Trw cycles can be inserted by means of the RCD bits in MCR, and the number of cycles
from CE assertion to BS assertion and write data output can be varied between 1 and 4.
