#define _NF_C_

void nfc_read_spare_byte	(	U8 _MEM_TYPE_SLOW_ *	p_byte,
		U8	n_byte,
		U32	page_addr
	)

Reads the number spare bytes specified and stores them in a array.

Parameters

p_byte	pointer on the array in which are stored the spare bytes.
n_byte	number of spare bytes to read.
page_addr	absolute page address of the block.

Precondition

nf_init() should have been called before. The NF device should have been selected before with nf_select( id ).
