8.3.2
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].
8.3.2.1
Read: Anytime
Write: Bits 7, 1, 0 anytime
Bit 6 can be written anytime but always reads back as 0.
Bits 4:3 anytime DBG is not armed.

When disarming the DBG by clearing ARM with software, the contents of
bits[4:3] are not affected by the write, since up until the write operation,
ARM = 1 preventing these bits from being written. These bits must be
cleared using a second write if required.
