Multiple data memory access instructions
These instructions perform multiple data accesses. The incremental accesses are performed as
word accesses. The number of cycles is dependent on the number of registers to load or store,
n. The issue latency must be modified as follows:
The instructions in this group will be aborted immediately if any interrupts are pending, in order
to limit the interrupt latency.

• LDM and POPM will use an additional cycle if testing of R12 is performed
• LDM and POPM that updates PC will cause a change-of-flow, which is performed in parallel
• The issue latency for HSB accesses increases if the HSB bus is busy or the slave inserts wait
with the pointer writeback and therefore has a penalty of only one cycle.
