Section 10 DMA Controller (DMAC)
While data is being transferred, DDAR must be accessed in longwords. If the upper word and
lower word are read separately, incorrect data may be read from since the contents of DDAR
during the transfer may be updated regardless of the access by the CPU. Moreover, DDAR for the
channel being transferred must not be written to.
(3)
A DMA transfer decrements the contents of DTCR by the transferred bytes. When byte data is
transferred, DTCR is decremented by 1. When word data is transferred, DTCR is decremented by
2. When longword data is transferred, DTCR is decremented by 4. However, when DTCR = 0, the
contents of DTCR are not changed since the number of transfers is not counted.
While data is being transferred, all the bits of DTCR may be changed. DTCR must be accessed in
longwords. If the upper word and lower word are read separately, incorrect data may be read from
since the contents of DTCR during the transfer may be updated regardless of the access by the
CPU. Moreover, DTCR for the channel being transferred must not be written to.
When a conflict occurs between the address update by DMA transfer and write access by the CPU,
the CPU has priority. When a conflict occurs between change from 1, 2, or 4 to 0 in DTCR and
write access by the CPU (other than 0), the CPU has priority in writing to DTCR. However, the
transfer is stopped.
(4)
DBSR is enabled in block or repeat transfer mode. Bits 31 to 16 in DBSR function as BKSZH and
bits 15 to 0 in DBSR function as BKSZ. The BKSZH bits (16 bits) store the block size and repeat
size and its value is not changed. The BKSZ bits (16 bits) function as a counter for the block size
and repeat size and its value is decremented every transfer by 1. When the BKSZ value is to
change from 1 to 0 by a DMA transfer, 0 is not stored but the BKSZH value is loaded into the
BKSZ bits.
Since the upper 16 bits of DBSR are not updated, DBSR can be accessed in words.
DBSR for the channel being transferred must not be written to.
