Section 14 Direct Memory Access Controller (DMAC)
14.2.3
The DMA transfer count registers 0 to 3 (DMATCR0 to DMATCR3) are 24-bit read/write
registers that specify the DMA transfer count (bytes, words, or longwords). The number of
transfers is 1 when the setting is H'000001, and 16777216 (the maximum) when H'000000 is set.
During a DMA transfer, these registers indicate the remaining transfer count.
To transfer data in 16 bytes, one 16-byte transfer (128 bits) counts one.
The upper eight bits in DMATCR are always read as 0 and should only be written with 0.
Initial values are undefined after a reset. The previous value is held in standby mode.
