VRH and VRL QADC Reference Supplies
MPC562BC cut-away pads VRH and VRL provide connection to MPC562 VDDA and VSSA for the VRH and VRL reference
signals respectfully. One or both of these pads may be cut to apply an external reference voltage to the QADC PORT.
QSM_PORT
The QSM (Queued Serial Module) Ports provide access to the MPC562 QSM I/O ports, SCI ports, SPI ports, CAN ports and 2
Interrupt signals on a 20 pin header. The signals are provided directly from the MPC562. User should note other connections and
options for the communication interfaces mentioned earlier in the manual before applying these ports.
