Chip-Select Signals S3 (switch 2 and 3)
The C161 Controller provides up to five Chip-Select Signals at Port
P6. The number of Chip-Select Signals active can be defined during
system reset through configuring P0.9 and P0.10. This configuration
can be done with DIP-Switch S3 (switch 2 and 3). These pins are
open in the default configuration meaning that all Chip-Select Signals
are active. Please note that /CS0 and /CS1 are used to control the
Flash devices on U8 and U9 and the RAM on U10 and U11. Hence
3 Chip-Select Signals are available for other purposes.

The C161 controller family allows user configuration of the number
of address-lines available for segment addressing at port P4. The

the number of active address lines. This configuration can be done
with DIP-Switch S3 (switch 4 and 5).
