Abstract:
A process of operating a microprocessor comprising:A. starting the microprocessor by receiving power in the microprocessor;B. initially setting a first number, defining a number of wait states, in a first register by loading data signals representing the first number into the first register from a data bus that extends to an external device;C. initially setting a second number, defining a number of wait states, in a second register by loading data signals representing the second number into the second register from the data bus;D. changing one of the first and second numbers to a third number by executing a software instruction to load data signals representing the third number into one of the first and second registers from the data bus; andE. using the number in one of the registers to insert that number of wait states between addressing the external device and receiving data from the external device.
