ABSTRACT:
A CPU (central processing unit) including an instruction processor and a data processor is connected with a ROM (read only memory) bus, a RAM (random access memory) bus, and an IO (input-output) bus for inputting/outputting data independently of the ROM and RAM buses. A rewritable register included in a memory access controller stores a set value of the number of wait cycles in an access to a ROM, a set value of the number of wait cycles in an access to a RAM, and a set value for switching an input path in the data processor. These set values can be varied according to a cycle time of a CPU clock signal. In accordance with these set values, insertion of wait cycles in the instruction processor and the data processor is controlled, and it is determined whether or not an input of the data processor is latched.
