The host communicates to the On-Chip Debugger by sending OCD commands using the
DBG interface. During normal operation, only a subset of the OCD commands are avail-
able. In DEBUG mode, all OCD commands become available unless the user code and
control registers are protected by programming the Flash Read Protect Option bit (
The Flash Read Protect Option bit prevents the code in memory from being read out of the

commands are disabled. Table 93 on page 148 is a summary of the On-Chip Debugger
commands. Each OCD command is described in further detail in the bulleted list follow-
ing this table. Table 93 also indicates those commands that operate when the device is not
in DEBUG mode (normal operation) and those commands that are disabled by program-
ming the Flash Read Protect Option bit.
