| IFX_INLINE boolean IfxDma_isChannelReset | ( | Ifx_DMA * | dma, |
| IfxDma_ChannelId | channelId | ||
| ) |
Return the status of a DMA channel (reset / not reset)
- Parameters
-
dma pointer to DMA module channelId DMA channel number
- Returns
- TRUE if the channel is reset FALSE if the channel is not reset
// check whether the channel is reset or not and also the hardware trigger disabled
if (IfxDma_isChannelReset(chn[0].dma, chn[0].channelId) &&
(!IfxDma_isChannelTransactionEnabled(chn[0].dma, chn[0].channelId))) {
// Dma is out of RESET and there is no hardware request enabled
IfxDma_Dma_startChannelTransaction(&chn[0]);
}
| IFX_INLINE void IfxDma_resetChannel | ( | Ifx_DMA * | dma, |
| IfxDma_ChannelId | channelId | ||
| ) |
Reset the channel.
- Parameters
-
dma pointer to DMA module channelId DMA channel number
- Returns
- None
// Apply reset to the channel
IfxDma_resetChannel(chn[0].dma, chn[0].channelId);
