19.3
A summary of the registers associated with the DBG sub-block is shown in
descriptions of the registers and bits are given in the subsections that follow.
19.3.1
This section consists of the DBG control and trace buffer register descriptions in address order. Each
comparator has a bank of registers that are visible through an 8-byte window between 0x0028 and 0x002F
in the DBG module register address map. When ARM is set in DBGC1, the only bits in the DBG module
registers that can be written are ARM, TRIG and COMRV[1:0]
