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
