Functions

NRF_STATIC_INLINE uint32_t nrf_ficr_codepagesize_get(NRF_FICR_Type const *p_reg)

Function for getting the size of the code memory page.

Parameters:

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

Returns:

Code memory page size in bytes.

NRF_STATIC_INLINE uint32_t nrf_ficr_codesize_get(NRF_FICR_Type const *p_reg)

Function for getting the size of the code memory rendered as number of pages.

Parameters:

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

Returns:

Code memory size rendered as number of pages.

NRF_STATIC_INLINE uint32_t nrf_ficr_deviceid_get(NRF_FICR_Type const *p_reg, uint32_t reg_id)

Function for getting the unique device identifier.

Parameters:

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

  • reg_id – [in] Register index.

Returns:

Unique device identifier.

NRF_STATIC_INLINE uint32_t nrf_ficr_nfc_tagheader_get(NRF_FICR_Type const *p_reg, uint32_t tagheader_id)

Function for getting the default header values for the NFC tag.

Parameters:

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

  • tagheader_id – [in] Tag header index.

Returns:

The default header value of the NFC tag for the specified header index.
