Function Documentation

memoryMap_Read32()

InterStatus memoryMap_Read32	(	const Address	address,
		UInt32 *	data )

memoryMap_Read32.

Reads 32-bit of data from the specified address.

Parameters

[in]	address	The address from which the data is to be read.
[out]	data	Pointer to store the read data.

Returns

InterStatus - Interface status return code, If no error occurs during the operation of the function, it returns INTF_SUCCESS. Otherwise related error message is returned.

Return values

INTF_SUCCESS	: Success.
ERR_MMAP_FAIL_TO_MAP	: Unable to read to a certain register.
