1
The Nexus specification labels active low signals with a forward slash (/) before the signal name.
2
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.
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.
