6.3.2 Register Descriptions
This section consists of the S12XDBG 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 S12XDBG module register address map. When ARM is set in DBGC1, the only bits in the
S12XDBG module registers that can be written are ARM, TRIG, and COMRV[1:0]
