19.12.23 DMA Channel Enable Register
Name:
Access Type:
Offset:
Reset Value:
• CH_EN_WE[11:8]: Channel Enable Write Enable
The channel enable bit, CH_EN, is only written if the corresponding channel write enable bit, CH_EN_WE, is asserted on
the same System Bus write transfer.
For example, writing 0x101 writes a 1 into ChEnReg[0], while ChEnReg[7:1] remains unchanged.
• CH_EN[3:0]
Enables/Disables the channel. Setting this bit enables a channel, clearing this bit disables the channel.
The ChEnReg.CH_EN bit is automatically cleared by hardware to disable the channel after the last System Bus transfer of
the DMA transfer to the destination has completed.Software can therefore poll this bit to determine when a DMA transfer
has completed.
