Description
Mask Protocol Error. When set, masks protocol error channel inter-
rupts for this logical channel. This bit valid for all Rx channel types.
This is valid for asynchronous and control Tx channels only.
Mask Detect Break. When set, masks detect break channel interrupt
for this logical channel. This bit is valid for asynchronous and con-
trol channels only.
Masks Receive Service Request. When set, masks Rx channel service
request interrupts for this logical channel.
Mask Buffer Done. When set, masks buffer done channel interrupts
for this logical channel.
Masks Transmit Service Request. When set, masks Tx channel ser-
vice request interrupts for this logical channel.
Mask Buffer Start. When set, masks buffer start channel interrupts
for this logical channel.
Mask Buffer Error. When set, masks buffer error channel interrupts
for this logical channel.
Reserved
Mask Lost Frame Synchronization. When set, masks lost frame syn-
chronization channel interrupts for this logical channel.
Reserved
Channel x Mode Select.
00 = Ping-pong DMA mode (default)
01 = Circular buffering DMA
10 = I/O mode enable
11 = Reserved
Frame Synchronization Enable. When set, enables streaming chan-
nel frame synchronization for this logical synchronous channel.
