Programmer Interface: Control Registers

The System Trace Module implements the Debug Module Base Register Map. The reset values are listed below.

Table 29 STM base register reset values
address name description reset value
0x0000 MOD_VENDOR module vendor 0x0001
0x0001 MOD_TYPE module type identifier 0x0004
0x0002 MOD_VERSION module version 0x0000
0x0003 MOD_CS module control and status 0x0000
0x0004 MOD_EVENT_DEST destination of debug events 0x0000

Additionally, it implements the following control registers for module-specific functionality.
