ABSTRACT:
An in-circuit emulation capability mode incorporated in an integrated circuit. The in-circuit emulation capability mode disables the microcontroller of the integrated circuit and allows use of an external in-circuit emulator device to test and debug the integrated circuit without the necessity of physically replacing the microcontroller with in-circuit emulator hardware. The in-circuit emulation capability mode is suitable for any integrated circuit, however, it has been found that integrated circuits incorporating an in-circuit emulation capability mode are especially suitable for incorporation into the base and handset units of a cordless telephone that integrates the speech, control channels, and microcontroller portions of a modem, and the man-machine interface functions of a cordless telephone.
