Section 9 DMA Controller (DMAC)
(6)
When an NMI interrupt is requested, the DTE bits for all the channels are cleared to 0 and the
ERRF bit in DMDR_0 is set to 1. When an NMI interrupt is requested during a DMA transfer, the
transfer is forced to stop. To perform DMA transfer after an NMI interrupt is requested, clear the
ERRF bit to 0 and then set the DTE bits for the channels to 1.
The transfer end timings after an NMI interrupt is requested are shown below.
(a)
In dual address mode, a DMA transfer is completed after completion of the write cycle for one
transfer unit.
In single address mode, a DMA transfer is completed after completion of the bus cycle for one
transfer unit.
(b) Block Transfer Mode
A DMA transfer is forced to stop. Since a 1-block size of transfers is not completed, operation is
not guaranteed.
In dual address mode, the write cycle corresponding to the read cycle is performed. This is similar
to (a) in normal transfer mode.
(7)
When an address error occurs, the DTE bits for all the channels are cleared to 0 and the ERRF bit
in DMDR_0 is set to 1. When an address error occurs during a DMA transfer, the transfer is
forced to stop. To perform a DMA transfer after an address error occurs, clear the ERRF bit to 0
and then set the DTE bits for the channels.
The transfer end timing after an address error is the same as that after an NMI interrupt.
(8)
The DMAC is initialized by a reset and a transition to the hardware standby mode. A DMA
transfer is not guaranteed.
