USER’S MANUAL
For load with update and store with update instructions, where RA = 0, the EA is writ-
ten into R0. For load with update instructions, where RA = RT, RA is boundedly unde-
fined.
For these types of instructions, EA must be a multiple of four. If it is not, the system
alignment error handler is invoked. For a lmw instruction (if RA is in the range of reg-
isters to be loaded), the instruction completes normally. RA is then loaded from the
memory location as follows:
Load string instructions behave the same as load multiple instructions, with respect to
invalid format in which RA is in the range of registers to be loaded. In case RA is in the
range, it is updated from memory.
For these type of instructions, EA must be a multiple of four. If it is not, the system
alignment error handler is invoked.
For Load and Store with update instructions, if RT = 0 then the EA is written into R0.
In case the operand falls in the range of a single denormalized number the floating-
point assist interrupt handler is invoked.
Refer to RCPU Reference Manual (Floating-Point Assist for Denormalized Operands)
for complete description of handling denormalized floating-point numbers.
In case the operand falls in the range of a single denormalized number, the floating-
point assist interrupt handler is invoked.
In case the operand is ZERO it is converted to the correct signed ZERO in single-pre-
cision format.
In case the operand is between the range of single denormalized and double denor-
malized it is considered a programming error. The hardware will handle this case as if
the operand was single denormalized.
In case the operand falls in the range of double denormalized numbers it is considered
a programming error. The hardware will handle this case as if the operand was ZERO.
