Data Structures
struct	WDOG_REGISTERS_T
	the struct we use so we can address registers using field names More...
struct	tr_hal_wdog_settings_t

Macros
#define	CHIP_MEMORY_MAP_WDOG_BASE   (0x40010000UL)
	chip register addresses section 2.2 of the data sheet explains the Memory map. this gives the base address for how to write the chip registers the chip registers are how the software interacts and configures the HAL peripherals. We create a struct below that addresses the individual registers. This makes it so we can use this base address and a struct field to read or write a chip register
