* - LA_FP_FACTOR

* - LA_FP_TO_REAL(val)
*
* Some scenarios require additional accuracy than what can be provided with
* T12X_LA_FP_FACTOR. For these special cases we use the following additional
* fixed point factor:- T12X_LA_ADDITIONAL_FP_FACTOR. Fixed point values which
* use the addtional fixed point factor have a suffix of "_fpa" or "_FPA" in
* their name. Macros used to convert between fpa values and other forms (i.e.
* fp and real) are as follows:
* - LA_FP_TO_FPA(val)
