READ NATIVE MAX ADDRESS (F8)
This command posts the maximum address intrinsic to the device, which can be set by the
SET MAX ADDRESS command. Upon receipt of this command, the device sets the BSY bit
and indicates the maximum address in the DH, CH, CL and SN registers. Then, it clears BSY
and generates an interrupt.
