Section 14 Direct Memory Access Controller (DMAC)
14.3.5
TCR are 32-bit readable/writable registers that specify the DMA transfer count. The number of
transfers is 1 when the setting is H'00000001, 16,777,215 when H'00FFFFFF is set, and
16,777,216 (the maximum) when H'00000000 is set. During a DMA transfer, these registers
indicate the remaining transfer count.
The upper eight bits of TCR (bits 31 to 24) are always read as 0, and the write value should always
be 0. The initial value is undefined.
