Section 6 Instruction Descriptions
6.5.11
Description
When FPSCR.PR = 0, this instruction arithmetically multiplies the two single-precision floating-
point numbers in FR0 and FRm, arithmetically adds the contents of FRn, and stores the result in
FRn.
When FPSCR.enable.O/U/I is set, an FPU exception trap is generated regardless of whether or not
an exception has occurred. When an exception occurs, correct exception information is reflected in
FPSCR.cause and FPSCR.flag, and FRn is not updated. Appropriate processing should therefore
be performed by software.
If FPSCR.PR = 1, the instruction is handled as an illegal instruction.
