<p>NAND Controller functions. </p>
<pre class="fragment"> ===============================================================================
##### NAND Controller functions #####
===============================================================================
[..] The following sequence should be followed to configure the FSMC to interface
with 8-bit or 16-bit NAND memory connected to the NAND Bank:
(#) Enable the clock for the FSMC and associated GPIOs using the following functions:
(++) RCC_AHB3PeriphClockCmd(RCC_AHB3Periph_FSMC, ENABLE);
(++) RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOx, ENABLE);
(#) FSMC pins configuration
(++) Connect the involved FSMC pins to AF12 using the following function
GPIO_PinAFConfig(GPIOx, GPIO_PinSourcex, GPIO_AF_FSMC);
(++) Configure these FSMC pins in alternate function mode by calling the function
GPIO_Init();
(#) Declare a FSMC_NANDInitTypeDef structure, for example:
FSMC_NANDInitTypeDef FSMC_NANDInitStructure;
and fill the FSMC_NANDInitStructure variable with the allowed values of
the structure member.
(#) Initialize the NAND Controller by calling the function
FSMC_NANDInit(&amp;FSMC_NANDInitStructure);
(#) Then enable the NAND Bank, for example:
FSMC_NANDCmd(FSMC_Bank3_NAND, ENABLE);
(#) At this stage you can read/write from/to the memory connected to the NAND Bank.
[..]
(@) To enable the Error Correction Code (ECC), you have to use the function
FSMC_NANDECCCmd(FSMC_Bank3_NAND, ENABLE);
[..]
(@) and to get the current ECC value you have to use the function
ECCval = FSMC_GetECC(FSMC_Bank3_NAND); </pre> <h2 class="groupheader">Function Documentation</h2>
