Table 6.2.1 On-Chip Peripherals Memory Map
6.2.3
The W90N740 address bus generation is depended on the required data bus width of each memory
bank. The data bus width is determined by DBWD bits in each bank’s control register.
The maximum accessible memory size of each external IO bank is 32M bytes .
