The mode must be set once and only once after initialization. With the RX62N SDRAMC, the SDRAM mode register can be written automatically by setting the SDRAM mode register (SMOD). Table 4 lists the setting values. (1) Mode register The RX62N SDRAMC operates with a burst length of 1. Operation is not guaranteed if a burst length other then 1 is set. This application note uses a burst length of 1, a column latency of 3 cycles, and single access mode.
