For devices that have more than one memory space (see Figure 4−34), an
access to bank 0 in one space does not interfere with an access to bank 0 in
another memory space, and no pipeline stall occurs.
The internal memory of the C67x DSP family varies from device to device. See
the device-specific data manual to determine the memory spaces in your device.
