Continue to next buffer descriptor.
Final buffer descriptor. Stop DMA operation upon completion of this transfer.
Use sequential address for next buffer descriptor. The link address field is not
present in this buffer descriptor, which is now 12 bytes long.
Use the link address field as a pointer to the next buffer descriptor. This buffer
descriptor is 16 bytes long.
No special treatment for last byte.
Internal Source: status byte written to initial buffer descriptor before last data.
Internal Destination: Last byte written to offset address for frame termination.
All others: No effect.
No interrupt on completing this transfer.
Interrupt on completing this transfer.
Source address is fixed internal I/O (two-byte) address.
Source address is fixed external I/O (two-byte) address.
Source address is memory (three-byte) address, auto-decrement.
Source address is memory (three-byte) address, auto-increment.
Destination address is fixed internal I/O (two-byte) address.
Destination address is fixed external I/O (two-byte) address.
Destination address is memory (three-byte) address, auto-decrement.
Destination address is memory (three-byte) address, auto-increment.
