Finds the approximate value (absolute error less than ±2^–21) of the sine and cosine of
the angle indicated by FPUL as a single-precision floating-point number, and writes the
sine value to FRn and the cosine value to FR[n+1]. As this is an approximate operation
instruction, it always generates an inexact exception request (even when the input is
zero).
If the I bit in the FPSCR.enable field is enabled, an FPU exception trap will be raised
regardeless of the exception occurrence, FPSCR.cause and FPSCR.flag fields reflect the
actual FPU exception status, and DRn does not change. Appropriate actions must be
taken by software.
