S12S Debug Module (S12SDBGV2)
6.3.2.8.8
Read: If COMRV[1:0] = 00
Write: If COMRV[1:0] = 00 and DBG not armed.
6.4
This section provides a complete functional description of the DBG module. If the part is in secure mode,
the DBG module can generate breakpoints but tracing is not possible.
6.4.1
Arming the DBG module by setting ARM in DBGC1 allows triggering the state sequencer, storing of data
in the trace buffer and generation of breakpoints to the CPU. The DBG module is made up of four main
blocks, the comparators, control logic, the state sequencer, and the trace buffer.
The comparators monitor the bus activity of the CPU. All comparators can be configured to monitor
address bus activity. Comparator A can also be configured to monitor databus activity and mask out
individual data bus bits during a compare. Comparators can be configured to use R/W and word/byte
access qualification in the comparison. A match with a comparator register value can initiate a state
sequencer transition to another state (see

Functional Description
S12SDBG Operation
Comparator Data High Mask Bits — The Comparator data high mask bits control whether the selected
comparator compares the data bus bits [15:8] to the corresponding comparator data compare bits. Data bus
comparisons are only performed if the TAG bit in DBGACTL is clear
0 Do not compare corresponding data bit Any value of corresponding data bit allows match.
1 Compare corresponding data bit
Bit 7
Comparator Data Low Mask Bits — The Comparator data low mask bits control whether the selected
comparator compares the data bus bits [7:0] to the corresponding comparator data compare bits. Data bus
comparisons are only performed if the TAG bit in DBGACTL is clear
0 Do not compare corresponding data bit. Any value of corresponding data bit allows match
1 Compare corresponding data bit
