NdisReadRegisterUchar is called by the miniport driver to read a UCHAR from a memory-mapped device register.
void NdisReadRegisterUchar( Register, Data );
Pointer to the memory-mapped register. This virtual address must fall within a range returned by an initialization-time call to NdisMMapIoSpace.
Pointer to the caller-supplied variable in which this function returns the UCHAR read from Register .
If a driver calls this function, a NIC's device registers must be mapped to noncached memory during driver initialization.
