3.1.3.1 Internal Controller Interrupt Input (IRQ9:8)
This is the interrupt input to the internal controller. Use this input, for example, to control (using
dedicated firmware) the MB86373 (MPEG2 decoder LSI) with the internal controller. When not in
use, connect the input to either OPEN or VDDE (fixed to High).
3.1.3.2 Host Interrupt Output (XEXTIRPT)
This is the interrupt output from the internal controller to the external host. The firmware
dedicated to the internal controller notifies the external host of the end of command processing,
for example. (For more information, see "MB86391 Control Protocol Command Specification
(Parallel I/F)").
