Functions

NRF_STATIC_INLINE void nrf_vmc_ram_block_config(NRF_VMC_Type *p_reg, uint8_t ram_block_num, uint32_t power_mask, uint32_t retention_mask)

Function for setting power configuration for the particular RAM block.

Note

Overrides current configuration.

Parameters:

  • p_reg – [in] Pointer to the structure of registers of the peripheral.

  • ram_block_num – [in] RAM block number.

  • power_mask – [in] Bitmask with sections configuration of particular RAM block. nrf_vmc_power_t should be use to prepare this bitmask.

  • retention_mask – [in] Bitmask with sections configuration of particular RAM block. nrf_vmc_retention_t should be use to prepare this bitmask.

NRF_STATIC_INLINE void nrf_vmc_ram_block_clear(NRF_VMC_Type *p_reg, uint8_t ram_block_num)

Function for clearing power configuration for the particular RAM block.

Parameters:

  • p_reg – [in] Pointer to the structure of registers of the peripheral.

  • ram_block_num – [in] RAM block number.

NRF_STATIC_INLINE void nrf_vmc_ram_block_power_set(NRF_VMC_Type *p_reg, uint8_t ram_block_num, nrf_vmc_power_t sect_power)

Function for setting power configuration for the particular RAM block.

Parameters:

  • p_reg – [in] Pointer to the structure of registers of the peripheral.

  • ram_block_num – [in] RAM block number.

  • sect_power – [in] Paricular section of the RAM block.

NRF_STATIC_INLINE void nrf_vmc_ram_block_power_clear(NRF_VMC_Type *p_reg, uint8_t ram_block_num, nrf_vmc_power_t sect_power)
