Operations in these modes are described in sections 8.4.2, I/O Mode, 8.4.3, Idle Mode, and 8.4.4,
Repeat Mode.
Description
Byte-size transfer
Word-size transfer
Description
MAR is incremented after each data transfer
• If DTSZ = 0, MAR is incremented by 1 after each transfer
• If DTSZ = 1, MAR is incremented by 2 after each transfer
MAR is decremented after each data transfer
• If DTSZ = 0, MAR is decremented by 1 after each transfer
• If DTSZ = 1, MAR is decremented by 2 after each transfer
