After one byte, word, or longword has been transferred, the bus is released. While the bus is
released, at least one CPU bus cycle is initiated.
Normal Transfer Mode (Cycle Steal Mode: Transfer Destination is USB): Figure 7.18 shows
an example of transfer when USB transfer is enabled, and word-size, normal transfer mode (cycle
steal mode) is performed from external 16-bit, 2-state access space to the FIFO in the USB.
After one byte, word, or longword has been transferred, the bus is released. While the bus is
released, at least one CPU bus cycle is initiated.
Block Transfer Mode (Cycle Steal Mode): Figure 7.19 shows an example of transfer when
TEND output is enabled, and word-size, block transfer mode (cycle steal mode) is performed from
external 16-bit, 2-state access space to external 16-bit, 2-state access space.
