STM32F429 Package size register

Hello all,

I want to move our STM32F429 from a BGA169 package to a LQFP100 package. A few pins need to be remapped. so I would like to know the package in run time.
in the STM32F429xx.h there is a definition for a Package size register
#define PACKAGE_BASE 0x1FFF7BF0U            /*!< Package size register base address     */
but there is nothing in the Reference manual about this register.
Does it exist? or is there a mean to know the package or pins number from software ?
