How to switch the CPU to 16 bits to access 16 bit device?


I have a CPLD (EPM240100T) chip that has data type of 16 bits, but the CPU access it using 8 bit. How do I switch the CPU mode (to 16 bits) to access this chip?

Any ideas will be appreicated.

Usually the first parts of code set that. What does the data sheet on that chip say?
