ARM9E-S debugger considerations
There are a number of differences between the ARM9TDMI and ARM9E-S that a
JTAG debugger must be aware of:
•
•
•
•
The EmbeddedICE version number in the debug channel status register is
different. See Debug comms channel control register on page 7-17.
From (test) reset, the ARM9E-S is configured into monitor mode debug. A
debugger requiring the ARM processor halt mode debug features must clear the
monitor mode enable bit in the debug control register. See Debug control register
on page C-34.
There are a number of instructions that have different cycle counts on ARM9E-S
to ARM9TDMI. In particular, the MRS instruction always requires two cycles to
execute on ARM9E-S. See Chapter 8 Instruction Cycle Times for more details on
instruction cycle timing.
The NV condition code cannot be used to provide a convenient single-cycle
non-interlocking
ARMv5TE architecture. A special opcode,
single-cycle, non-interlocking
UNPREDICTABLE part of the instruction space, so that its behavior cannot be
guaranteed over all ARM variants.
