Application note
Memory monitoring using JDC module
Introduction
The document describes how to implement an application allowing an external tool to
monitor the memory of the device by the JTAG pins. It uses the JTAG Data Communication
(JDC) module to implement this monitor using only JATG pins.
The JDC module captures data into a memory mapped register that can be accessed via
IPS for output via JTAG port.
The application is tested and validated using SPC574S60xx target and Lauterbach
TRACE32 as external tool but it is valid for all targets with JDC modules listed below:
• SPC574K70xx
• SPC57EM80xx
• SPC574S60xx
• SPC570S50xx
• SPC572L64xx
