Read) IN_DMA_Run Observation
0: DMA is stopped
Write) Ignore EPn_DMA_TTC_n register
0: DMA requests will be stopped if
1: DMA requests will be continued although
DMA State Monitoring
DMA Demand mode enable bit
0: Demand mode disable
1: Demand mode enable
Functionally separated into write and read
operation.
Write operation: "0" = Stop "1" = Run
Read operation: OUT DMA Run Observation
Start DMA operation.
0 = Stop
Set DMA mode.If the IN_RUN_OB has been
wrtten as 0 and EPn_DMA_TTC_n reaches 0,
DMA_MODE_EN bit will be cleared by USB.
0 = Interrupt mode
EPn_DMA_TTC_n reaches 0.
EPn_DMA_TTC_n reaches 0.
