about cordic16 IP

Hello.

I'm using the altera cordic core 16 for atan2 e magnitude calculation.

It works very well!

Can you tell me if this core is configurable for inverse cotangent calculation?

I need an IP for the ln (natural logaritmic) calculation, and cordic configured in hiperbolic mode do it.

But i do not know if the altera cordic 16 is configurable in iperbolic mode (for calculate inverse cotangent)
