    Abstract: PROBLEM TO BE SOLVED: To simultaneously use two pieces of different peripheral equipment capable of functioning by a single pin by providing process circuit mechanism and settable pin setting. SOLUTION: A multiplexer 14 is connected with a function circuit 12 via a communication line 18, connected with a pin P1 via a communication line 20, connected with a pin P2 via a communication line 22 and connected with a setting register 16 via a communication line 24. When a flag received from the setting register 16 is '1', the multiplexer 14 is operated so as to connect the function circuit 12 with the pin P1. When the flag received from the setting register 16 is 'zero', the multiplexer 14 is further operated so as to connect the function circuit 12 with the pin P2. Therefore, a user is able to transfer a function related to the function circuit 12 from one pin to another by using the multiplexer 14 and the setting register 16 by a circuit 10.

    Abstract: A device, system and method for providing access to user memory in emulator systems. The emulator system contains an emulator system memory, a user system memory and an emulator device. The emulator device operates in a mode where program execution instructions originate in the emulation memory while read and write instructions target the user memory. Logic included in the emulator chip directs the read and write memory accesses to the user memory while instructions are fetched from the emulator memory.
