SDRAM Writes

SDRAM writes are requested in the native interface by asserting the L_W_REQ signal high, and by driving the starting address and the burst size on the L_ADDR and L_B_SIZE signals respectively. A write can be requested with auto-precharge by asserting the L_AUTO_PCH signal along with the L_W_REQ signal.

The following are the rules for write requests in the native interface:

Note: The user logic must not rely on any fixed timing relationship between the L_W_REQ, L_D_REQ, and L_BUSY signals.
