Section 6 Instruction Descriptions
6.5.18
Description
When FPSCR.PR = 0: Arithmetically subtracts the single-precision floating-point number in FRm
from the single-precision floating-point number in FRn, and stores the result in FRn.
When FPSCR.PR = 1: Arithmetically subtracts the double-precision floating-point number in
DRm from the double-precision floating-point number in DRn, and stores the result in DRn.
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 or DRn is not updated. Appropriate processing should
therefore be performed by software.
