The AtaPortReadRegisterBufferUchar routine transfers a specified number of unsigned bytes from the HBA to a buffer.
Note The ATA port driver and ATA miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.
Register [in]Contains the register address where the transfer should begin. This address value must be within the range of mapped I/O space addresses that are obtained by a call to AtaPortGetDeviceBase.
Buffer [in]A pointer to the destination buffer.
Count [in]Specifies the number of bytes to read from the HBA.
