bit data width, chip system address bit [16:1] is used as the device’s address [15:0] and chip
system address bit [0] is useless.
When system access data width is lager than EBI data width, EBI controller will finish a system
access command by operating EBI access more than once. For example, if system requests a
32-bit data through EBI device, EBI controller will operate accessing four times when setting EBI
data width with 8-bit.
