S12S Debug Module (S12SDBGV2)
6.3.2.7.4
Read: If COMRV[1:0] = 11
Write: Never
DBGMFR is visible at 0x0027 only with COMRV[1:0] = 11. It features 3 flag bits each mapped directly
to a channel. Should a match occur on the channel during the debug session, then the corresponding flag
is set and remains set until the next time the module is armed by writing to the ARM bit. Thus the contents
are retained after a debug session for evaluation purposes. These flags cannot be cleared by software, they
are cleared only when arming the module. A set flag does not inhibit the setting of other flags. Once a flag
is set, further comparator matches on the same channel in the same session have no affect on that flag.
6.3.2.8
Each comparator has a bank of registers that are visible through an 8-byte window in the DBG module
register address map. Comparator A consists of 8 register bytes (3 address bus compare registers, two data
bus compare registers, two data bus mask registers and a control register). Comparator B consists of four
register bytes (three address bus compare registers and a control register). Comparator C consists of four
register bytes (three address bus compare registers and a control register).
Each set of comparator registers can be accessed using the COMRV bits in the DBGC1 register.
Unimplemented registers (e.g. Comparator B data bus and data bus masking) read as zero and cannot be
written. The control register for comparator B differs from those of comparators A and C.
6.3.2.8.1
The contents of this register bits 7 and 6 differ depending upon which comparator registers are visible in
the 8-byte window of the DBG module register address map.
