Please solve this problem as soon as possible thank you a lot

Q7. a) How many I/O ports are supported on ARM. Write their names and associate GPIO configuration registers. b) Calculate I/O addresses of GPIOB_MODER, GPIOB_OTYPER, GPIOB_OSPEEDR, GPIOB_PUDR, GPIOB_IDR, GPIOB_ODR, GPIOB_BSRR registers c)configure PAO as input and PA1 as output on STM32F405RG ARM microcontroller. Output type should be push-pull and output speed should be high and input type should be pull-up. Which registers will be used for this configuration and which bits of them will be used and what should be values needed for this configuration
