USER’S MANUAL
Command and data transfers initiated by the development system should clear bit 16.
The current implementation ignores this bit; however, Motorola reserves the right to
use this bit for future enhancements.
In order to provide for use of development tools when an MCU is installed in a system,
Motorola recommends that appropriate signal lines be routed to a male Berg connec-
tor or double-row header installed on the circuit board with the MCU, as shown in the
following figure.
