Section 6 Instruction Descriptions
6.5.19
Description
When FPSCR.PR = 0: Converts the single-precision floating-point number in FRm to a 32-bit
integer, and stores the result in FPUL.
When FPSCR.PR = 1: Converts the double-precision floating-point number in FRm to a 32-bit
integer, and stores the result in FPUL.
The rounding mode is always truncation.
