Macro for creating and initializing an NFC NDEF record descriptor for a Collision Resolution record.

This macro creates and initializes an instance of type nfc_ndef_record_desc and an instance of type nfc_ndef_ch_cr_rec, which together constitute an instance of an Collision Resolution record.

Use the macro NFC_NDEF_CR_RECORD_DESC to access the NDEF Collision Resolution record descriptor instance.

Parameters
[in]_nameName of the created record descriptor instance.
[in]_random_numberGenerated random number required to resolve a collision.
