2. If the flag is read at the same timing it is set to 1,
read.
the read data will be 0, but the internal state may
be the same as reading 1. Therefore, if 0 is written
to the flag, the flag will be cleared to 0 because the
internal state is the same as when writing 0 after
reading 1.
For details, refer to section 10.5.5, Notes on Using
Flag Bits.

Description
Address Error Flag
Indicates whether an address error has occurred by
the DMAC. When this bit is set, even if the DE bit in
CHCR and the DME bit in DMAOR are set to 1, DMA
transfer is not enabled. This bit can only be cleared by
writing 0 after reading 1.*
0: No DMAC address error
1: DMAC address error occurred
[Clearing condition]
•
NMI Flag
Indicates that an NMI interrupt occurred. When this bit
is set, even if the DE bit in CHCR and the DME bit in
DMAOR are set to 1, DMA transfer is not enabled. 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. Even if the NMI
interrupt is input while the DMAC is not in operation,
the NMIF bit is set to 1.
0: No NMI interrupt
1: NMI interrupt occurred
[Clearing condition]
•
Writing 0 after reading AE = 1*
Writing 0 after reading NMIF = 1*
