Abstract

Circuits, devices and methods are provided to manage modifications to protected registers within an implantable medical device (IMD). The circuit comprises a bus controller that includes an address register, an unlock register and a protected register (PR) enable unit. The PR enable unit sets a protect enable signal to an access state based on content loaded into the unlock register. A peripheral block includes a protected register that retains content for operating the IMD. The peripheral block includes a register access input to receive the protected enable signal. A PR write control unit is provided to enable an attempted write of the content from a data interface to the protected register when the protected enable signal has an access state.
