6.5.6.4 Interactive Mode

The Boot ROM provides interactive debugging capabilities to facilitate chip erase operations on protected devices (DAL < 0x2). This functionality is also available on unprotected devices.

It also allows the debugger to request a Reset. During interactive debugging, the host, debugger, and the target/device utilize the Boot Communication Channels to send a limited and predetermined set of commands and responses between each other. Refer to Boot Communication Channels for more information.

By convention, BCC0 is always used to send commands from the host to the target while BCC1 is always used to send responses from the target to the host.
