36 Nexus Development Interface (NDI)
36.1 Introduction
The Nexus Development Interface (NDI) block provides development support capabilities for
the SPC560P40/34 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 SPC560P40/34.
The NDI block interfaces to the e200z0, and internal buses to provide development support
as per the IEEE-ISTO 5001-2003 standard. The development support provided includes the
MCU’s internal memory map, and access to the e200z0 internal registers, via the JTAG port.
