Bit 6—Data Transfer Size (DTSZ): Selects the data size of each transfer.
Bit 5—Data Transfer Increment/Decrement (DTID): Selects whether to increment or
decrement the memory address register (MAR) after a data transfer in I/O mode or repeat mode.
MAR is not incremented or decremented in idle mode.
Bit 4—Repeat Enable (RPE): Selects whether to transfer data in I/O mode, idle mode, or repeat
mode.
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.
Bit 3—Data Transfer Interrupt Enable (DTIE): Enables or disables the CPU interrupt (DEND)
requested when the DTE bit is cleared to 0.

If DTSZ = 0, MAR is incremented by 1 after each transfer
If DTSZ = 1, MAR is incremented by 2 after each transfer
If DTSZ = 0, MAR is decremented by 1 after each transfer
If DTSZ = 1, MAR is decremented by 2 after each transfer
