    Hello, I hope someone help me.

1. In TS201, does it have some methods to modify interrution priority? Can I modify PMASK to up or down the interruption priority?

2. What is function of DP in TCB? How can I use it to mask higher priority of other interrution?

3. I use four external DMA channel to transmit data, but require the priority of four channels is equal, or when a channel is coming data, the channel improve its priority to mask other channel. How can I do? Please help me.
