Controlling Precharge Cycle
The number of precharge cycles (Tp) can be selected from one to four clock cycles by bits TPC1
and TPC0 in DRACCR. Set the bit according to the DRAM to be used and the frequency of this
LSI so that the number of precharge cycle can be optimal.
Figure 6.42 shows an access timing example when two Tp cycles are specified.
The setting of bits TPC1 and TPC0 affect the Tp cycle of a refresh cycle.
