14.1 Outline of the Real-Time Debugger (RTD)
The Real-Time Debugger (RTD) is a serial I/O through which to read or write to the internal RAM's
entire area using commands from outside the microprocessor. Because data transfers between the
RTD and internal RAM are performed using an internal dedicated bus independently of the M32R
CPU, operation can be controlled without having the stop the M32R CPU.
