Exception Processing PST = 0xC, {PST = 0xB,DD = destination}, // stack frame
The PST/DDATA specification for the reset exception is shown below:
Exception Processing PST = 0xC,
5-40
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.
