  • Semiconductor integrated circuit
    Patent number: 7484147
    Abstract: A semiconductor integrated circuit for intentionally and flexibly changing a monitoring subject bit if debugging is performed during software processing when a status change occurs. A replacement data register and a comparison address register, which are settable from a microprocessor, determine matching of an address input from the microprocessor and a comparison address value. When the addresses match in a test mode, instead of outputting normal status data, a predetermined value of the replacement data register is output in response to a read request from the microprocessor.
    Type: Grant
    Filed: August 14, 2006
    Date of Patent: January 27, 2009
    Assignee: Freescale Semiconductor, Inc
