Section 8 DMA Controller
Bit 7—Data Transfer Enable (DTE): Together with the DTME bit in DTCRB, this bit enables
or disables data transfer on the channel. When the DTME and DTE bits are both set to 1, the
channel is enabled. If auto-request is specified, data transfer begins immediately. Otherwise, the
channel waits for transfers to be requested. When the specified number of transfers have been
completed, the DTE bit is automatically cleared to 0. When DTE is 0, the channel is disabled and
does not accept transfer requests. DTE is set to 1 by reading the register when DTE is 0, then
writing 1.
If DTIE is set to 1, a CPU interrupt is requested when DTE is cleared to 0.
Bit 6—Data Transfer Size (DTSZ): Selects the data size of each transfer.
Bit 5—Source Address Increment/Decrement (SAID) and Bit 4—Source Address
Increment/Decrement Enable (SAIDE): These bits select whether the source address register
(MARA) is incremented, decremented, or held fixed during the data transfer.
