  • Architecture, circuitry and method for controlling a subsystem through a JTAG access port
    Patent number: 6918057
    Abstract: Architecture, circuitry, and methods are provided for programming, writing to, or reading from one or more integrated circuits which may be arranged upon a printed circuit board. Programming and read/write operations can, therefore, be done after integrated circuits are populated upon a printed circuit board to control those integrated circuits using a standard JTAG interface, well-known as the IEEE Std. 1149.1 interface. A shift register used to control one or more electronic subcomponents can be programmed, written to, or read from using JTAG programming languages. However, the shift register, or multiple shift registers, used to control electronic subcomponents need not be JTAG compliant.
