The STM32F series provides up to 68 maskable user interrupts for the STM32F10x
series, and 87 for the STM32F2xx and STM32F4xx series.
The NVIC registers are defined by the ARM standards but the STM32F series have some
additional limitations

@brief <b>libopencm3 STM32Fxx System Tick Timer</b>
@version 1.0.0
@author @htmlonly &copy; @endhtmlonly 2010 Thomas Otto <tommi@viadmin.org>
@date 19 August 2012
This library supports the System Tick timer in the
STM32F series of ARM Cortex Microcontrollers by ST Microelectronics.
The System Tick timer is part of the ARM Cortex core. It is a 24 bit
down counter that can be configured with an automatical reload value.
