Copy data from the MMIO region to system memory by using 16-bit access.
Copy data from the MMIO region specified by starting address StartAddress to system memory specified by Buffer by using 16-bit access. The total number of byte to be copied is specified by Length. Buffer is returned.
If StartAddress is not aligned on a 16-bit boundary, then ASSERT().
If Length is greater than (MAX_ADDRESS - StartAddress + 1), then ASSERT(). If Length is greater than (MAX_ADDRESS - Buffer + 1), then ASSERT().
If Length is not aligned on a 16-bit boundary, then ASSERT(). If Buffer is not aligned on a 16-bit boundary, then ASSERT().
StartAddress | The starting address for the MMIO region to be copied from. | |
Length | The size, in bytes, of Buffer. | |
Buffer | The pointer to a system memory buffer receiving the data read. |
