[in]	*memblock	The pointer to location stored required data to be written to card
[in]	blockNum	The block number to start writting
[in]	numOfBlock	Determine how many blocks will be written (from the starting block)

Returns:: MCI_FUNC_OK if all success

Here is the call graph for this function:

int32_t Lpc177x_8x_MciReadBlock	(	uint8_t *	destBlock,
		uint32_t	blockNum,
		uint32_t	numOfBlock
	)

Read data at a specific address to starting block with number of blocks will be read from first block.

At preparation
- Set MCI data control register, data length and data timeout
- Send CMD17 (READ_SINGLE_BLOCK) or CMD18 (READ_MULTIPLE_BLOCK) commands to card
- Enable interupt for MCI component
At completion
- RX_ACTIVE interrupt is occured
- Read data from FIFO register continuously until the data block length is reached to retrieve needed data

Parameters:

[in]	*destBlock	The pointer to location will captured data read from card
[in]	blockNum	The block number to start reading
[in]	numOfBlock	Determine how many blocks will be read (from the starting block)
