Communication Ports
On the MPC56x devices, some of the Nexus signals are shared with other pin functions. MPC56x
Signal Sharing shows the Nexus signal versus the MPC561/562/563/564 pins.

The Nexus specification labels active low signals with a forward slash (/) before the signal name.

The Nexus standard recommends that inputs should have 10K :pull-up resistors to VREF (2.6 volts).
Exception: The RSTI input should have a 10K :pull-down resistor. This is in line with the proposed new
standard.
3
This signal is needed only if control of EPEE or B0EPEE is required by the Nexus tool.
