STM32_CLOCK

#define STM32_CLOCK	(		val,
			mask,
			shift,
			reg
	)

Value:

        ((((reg) & STM32_CLOCK_REG_MASK) << STM32_CLOCK_REG_SHIFT) |    \
         (((shift) & STM32_CLOCK_SHIFT_MASK) << STM32_CLOCK_SHIFT_SHIFT) |      \

         (((val) & STM32_CLOCK_VAL_MASK) << STM32_CLOCK_VAL_SHIFT))

STM32H7 clock configuration bit field.

• reg (0/1) [ 0 : 7 ]
• shift (0..31) [ 8 : 12 ]
• mask (0x1, 0x3, 0x7) [ 13 : 15 ]
• val (0..3) [ 16 : 18 ]

Parameters

reg	RCC_DxCCIP register offset
shift	Position within RCC_DxCCIP.
mask	Mask for the RCC_DxCCIP field.
val	Clock value (0, 1, 2 or 3).
