Abstract
Disclosed approaches for controlling debug access to an integrated circuit (IC) device include receiving a debug packet by a debug interface circuit of the IC device. The debug interface circuit authenticates the debug packet in response to the debug packet having a command code that specifies enable debug mode or a command code that specifies disable debug mode. In response to the debug packet passing authentication and the command code specifying enable, the debug interface circuit enables debug mode of the IC device. In response to the debug packet passing authentication and the command code specifying disable, the debug interface circuit disables the debug mode of the IC device. In response to the debug packet failing authentication, the debug interface circuit rejects the debug packet.
