**
**     Description :
**         The L_shr_r function arithmetically shifts the input
**         variable x right n positions, sign extending the result.
**         If n is negative, the L_shr_r function arithmetically
**         shifts x left by -n bits, zero filling the least
**         significant bits. L_shr_r differs from L_shr in that
**         L_shr_r rounds the 32-bit fractional result.
**     Parameters  :
**         NAME            - DESCRIPTION
**         x               - The input data value.
**         n               - The number of bits to right shift x; n is
**                           signed and, if negative, implies a right
**                           shift.
**     Returns     :
**         ---             - The function returns the value x
**                           arithmetically shifted by n bits.
