Section 10 Bus State Controller (BSC)
10.3.2 Data Bus Width and Pin Function Setting for Individual Areas
In this LSI, the data bus width for CS0 can be set to 16 or 32 bits through external pins during a
power-on reset. The data bus width for CS1 to CS5 can be modified through register settings by a
program.
After a power-on reset, the LSI starts execution of the program stored in the external memory
allocated in CS0.
For details on pin function settings, see section 27, Pin Function Controller (PFC).
