Description
Indicates that an address error occurred during DMA
transfer. If this bit is set, DMA transfer is disabled even if
the DE bit in CHCR and the DME bit in DMAOR are set to
1. This bit can only be cleared by writing 0 after reading
1.
0: No DMAC address error
[Clearing condition]
Writing AE = 0 after AE = 1 read
1: DMAC address error occurs
Indicates that an NMI interrupt occurred. If this bit is set,
DMA transfer is disabled even if the DE bit in CHCR and
the DME bit in DMAOR are set to 1. This bit can only be
cleared by writing 0 after reading 1.
When the NMI is input, the DMA transfer in progress can
be done in one transfer unit. When the DMAC is not in
operational, the NMIF bit is set to 1 even if the NMI
interrupt was input.
0: No NMI interrupt
[Clearing condition]
Writing NMIF = 0 after NMIF = 1 read
1: NMI interrupt occurs
DMA Master Enable
Enables or disables DMA transfers on all channels. If the
DME bit and the DE bit in CHCR are set to 1, transfer is
enabled. In this time, all of the bits TE in CHCR, NMIF,
and AE in DMAOR must be 0. If this bit is cleared during
transfer, transfers in all channels are terminated.
0: Disables DMA transfers on all channels
1: Enables DMA transfers on all channels
