Abstract
A circuit for reading out address data applied to a memory in a one-chip microcomputer which does not have any address terminals but has input/output terminals. The circuit comprises a program counter for specifying reading out addresses of the memory. Transfer gates and a shift register are also provided. The transfer gates transfer the contents of the program counter to the shift register when an address output enable signal is applied to the transfer gates. The contents stored in the shift register are read out to an address output terminal connected to the shift register.
