transfer and the DMAC is awaiting the end of the transfer. After
the T1FHI start, the bus is released and the DMAC transitions to the TE state

transfers.
If the next transfer is executed in block transfer mode, the DMAC moves to the T1FH state after the
T2FH state. In other modes, if a wait has occurred, the DMAC transitions to the T1FHI state. If no
wait has occurred, the bus is released and the DMAC transitions to the TE state.
(13) TE state
The TE state corresponds to DMA transfer completion. The DMAC generates the internal DMA
transfer completion signal and various internal signals are initialized. After entering the TE state,
the bus invariably enters the TI state.
Note: The Flyby transfer mode is not supported on Jupiter.
