registers contains 32 bits with which 32 of the interrupts can be enabled. The STM32F103RB/C8 has 43 interrupts, so only two of the possible 16 registers are present. The number of interrupts is given in chapter 2.3.5 of the controller’s datasheet. So, to enable some interrupt x, the bit “x mod 32”
