The notes on using the following flag bits are described here.
• DMA channel control register (CHCR)
• DMA operation register (DMAOR)
If a flag is read at the same timing it is set to 1, 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.
In the case of using a flag, to prevent from unintentionally clearing the flag bit to 0, perform
read/write as follows:
(a) In the case of intended bit clear, write 0 to the flag bit after reading it as 1.
(b) In other cases, write 1 to the flag bit.
If a flag is not used, just writing 0 to the flag bit does not generate errors (in the case of intended
bit clear, write 0 to the flag bit after reading it as 1).
HE (Half-End) and TE (Transfer End Flag) bits
AE (Address Error Flag) and NMIF (NMI Flag) bits
