detected and data storage interrupt is never generated by the hardware. In the RCPU, the instruction can
be partially executed only in the case of the load/store instructions that cause multiple accesses to the
memory subsystem. These instructions are:
•
Multiple/string instructions
•
Unaligned load/store instructions
In the last case, the store instruction can be partially completed if one of the accesses (except the first one)
causes the data storage protection error. The implementation-specific data storage protection interrupt is
taken in this case. For the update forms, the update register (rA) is not altered.

Timer Facilities
Descriptions of the timebase and decrementer registers can be found in
Chapter 6, “System Configuration
,” and in
Chapter 8, “Clocks and Power Control
.”
3.15.7
Optional Facilities and Instructions
Any other OEA optional facilities and instructions (except those that are discussed here) are not
implemented by the RCPU hardware. Attempting to execute any of these instructions causes an
implementation dependent software emulation interrupt to be taken.
