Description
Controls the propagation of the uDMA done and active state to the
assigned peripheral. Specifically used for software channels.
Read as:
Bit [Ch] = 0: uDMA done and active state for channel Ch is not
blocked from reaching to the peripherals.
Note that the uDMA done state for channel [Ch] is blocked from
contributing to generation of combined uDMA done signal
Bit [Ch] = 1: uDMA done and active state for channel Ch is blocked
from reaching to the peripherals.
Note that the uDMA done state for channel [Ch] is not blocked from
contributing to generation of combined uDMA done signal
Write as:
Bit [Ch] = 0: Allows uDMA done and active stat to propagate to the
peripherals.
Note that this disables uDMA done state for channel [Ch] from
contributing to generation of combined uDMA done signal
Bit [Ch] = 1: Blocks uDMA done and active state to propagate to the
peripherals.
Note that this enables uDMA done for channel [Ch] to contribute to
generation of combined uDMA done signal.
