Description
Reflects the uDMA done status for the given channel, channel [Ch].
It's a sticky done bit. Unless cleared by writing a 1, it holds the value
of 1.
Read as:
Bit [Ch] = 0: Request has not completed for channel Ch
Bit [Ch] = 1: Request has completed for the channel Ch
Writing a 1 to individual bits would clear the corresponding bit.
Write as:
Bit [Ch] = 0: No effect.
Bit [Ch] = 1: The corresponding [Ch] bit is cleared and is set to 0
