33.6.3 Border Management
When the memory row boundary has been reached, an automatic page break is inserted. In this case, the SDRAMC generates a precharge command, activates the new row and initiates a read or write command. To comply with SDRAM timing parameters, an additional clock cycle is inserted between the precharge and the active command (tRP) and between the active and the read command (tRCD). See the following figure.
