Nexus Development Interface (NDI)
The NDI block provides real-time development support capabilities for the SPC560Px Power
Architecture based MCU in compliance with the IEEE-ISTO 5001-2003 standard. This
development support is supplied for MCUs without requiring external address and data pins
for internal visibility. The NDI block is an integration of several individual Nexus blocks that
are selected to provide the development support interface for this device. The NDI block
interfaces to the host processor and internal busses to provide development support as per
the IEEE-ISTO 5001-2003 Class 2+ standard. The development support provided includes
access to the MCUs internal memory map and access to the processors internal registers
during run time.
The Nexus Interface provides the following features:

IEEE 1149.1 JTAG controller
The JTAG Controller (JTAGC) block provides the means to test chip functionality and
connectivity while remaining transparent to system logic when not in test mode. All data
input to and output from the JTAGC block is communicated in serial format. The JTAGC
block is compliant with the IEEE standard.
Nominal temperature range from –40 °C to 150 °C
