4.8 Debug Scan Chains
The device contains an ICEPICK module to access the debug scan chains. Debug scan chain #0 handles
the access to the CPU, to the ETM-R4 (External Trace Macrocell), to the POM (Parameter Overlay
Module) and to the TPIU (Test Port Interface Unit). Debug scan chain #1 handles the access to the Ram
Trace Port (RTP) and the Data Modification Module (DMM) which each incorporate a dedicated TAP (Test
Access Port) controller. Each module is selected via its scan chain number. The IcePick scan ID is
0x80206D05, which is the same number as the device ID.
