Parameters
mt2Changed
[in] Memory change type. Indicates one of the following types of change:- Virtual memory
- Physical memory
- Peripheral I/O
- CPU register context
Address
[in] Starting address of the data buffer to be accessed on the target.bAddressSpace

- 0 = Physical memory
- 1 = Peripheral I/O if not memory mapped
- 2...255 = free for custom use
dwNbElemChanged
[in] Number of elements of bAccessWidthInBytes to be accessed.bAccessWidthInBytes
[in] Data width in bytes, such as byte=1, word=2, dword=4, and so on.
