What is the maximum external SDRAM that i can interface with LPC4337. UM10503 document, table 412 says I can interface three 256MB and one 128MB. What is MB? is ti MegaBytes or Megabits? i have read on some forums that this is Megabits. If it is Megabits why does adress range in table 412 of UM10503 seems bigger than its max capacity?
