For a single access or an incremented burst of unspecified length, the SDRAM Controller antici-
pates the next access. While the last value of the column is returned by the SDRAM Controller
on the bus, the SDRAM Controller anticipates the read to the next column and thus anticipates
the CAS latency. This reduces the effect of the CAS latency on the internal bus.
For burst access of specified length (4, 8, 16 words), access is not anticipated. This case leads
to the best performance. If the burst is broken (border, busy mode, etc.), the next access is han-
dled as an incrementing burst of unspecified length.
When the memory row boundary has been reached, an automatic page break is inserted. In this
case, the SDRAM controller generates a precharge command, activates the new row and initi-
ates a read or write command. To comply with SDRAM timing parameters, an additional clock
cycle is inserted between the precharge/active (t
mand. This is described in
