Exception ProcessingPST = 0xC,{PST = 0xB,DD = destination},// stack frame
The PST/DDATA specification for the reset exception is shown below:
Exception ProcessingPST = 0xC,
The initial references at address 0 and 4 are never captured nor displayed since these accesses are treated
as instruction fetches.

For JMP and JSR instructions, the optional target instruction address is displayed only for those effective address
fields defining variant addressing modes. This includes the following <ea>x values: (An), (d16,An), (d8,An,Xi),
(d8,PC,Xi).
For Move Multiple instructions (MOVEM), the processor automatically generates line-sized transfers if the operand
address reaches a 0-modulo-16 boundary and there are four or more registers to be transferred. For these line-sized
transfers, the operand data is never captured nor displayed, regardless of the CSR value.
The automatic line-sized burst transfers are provided to maximize performance during these sequential memory
access operations.
During normal exception processing, the PST output is driven to a 0xC indicating the exception processing state. The
exception stack write operands, as well as the vector read and target address of the exception handler may also be
displayed.
