Does anyone knows how to control the chip select(cs) on the evaluation board? IN other words writing to which addresses will render the cs high or low. THanks
This is documented in the MCBx51 user's guide that you can download from http://www.keil.com/mcbx51. Take a look to page 14, MAP1, MAP0: the tables list the address range. Also you can find it directly in the Schematic that is provided in Chapter 3. Hardware.
