MOTOROLA
The BKAR allows a full 32-bit address to be loaded. This address is qualified in various
ways using the BKCR. If no address is desired, the V-bit in the BKCR may be cleared.
The BKCR allows the user to check many combinations of function codes before causing
a breakpoint match. Nine bits in the BKCR allow such possibilities as excluding the IDMA
and SDMA function codes and the user and supervisor programs, but including user and
supervisor data.
The breakpoint logic can cause a breakpoint match for read accesses only, write access-
es only, or both read and write accesses.
The breakpoint logic can cause a breakpoint match for accesses to the specified address
with a size of byte, word, three byte, long word, or any size.
If desired, the breakpoint match can occur in a region larger than just one address. Block
sizes may be defined to be the block of memory in which the address resides. The blocks
sizes may be 2K, 8K, or 32K bytes.
Additionally, the breakpoint match can be defined to occur at every address except the
address or address block that is specified. This feature allows the user to single step all
his program code. The breakpoint logic is then used to mask off the user’s monitor/debug-
ger. The monitor/debugger thus resides within the programmable block specified by the
breakpoint logic.
The breakpoint logic can also work with external masters, such as an external MC68040,
MC68030, or QUICC. The BKPT pin is asserted when a match is detected.
In the case of an external MC68040, the user may have to set the TSS40 bit in the GMR
to allow enough setup time for the address comparison logic. Also, in the case of an ex-
ternal MC68040, the comparison is only made on the first accesses of an MC68040 burst
access (i.e., the address comparison of the breakpoint logic is performed only when the
MC68040 TS pin is asserted).
