Beispiel #1

Datei: gpmi.cpp Projekt: Alexlcb/rt-thread

void gpmi_init_dma_channel(int u32ChipNumber)
{
    reg32_t r32ChipDmaNumber = NAND0_APBH_CH + u32ChipNumber;
    reg32_t chipDmaMask = 1 << r32ChipDmaNumber;

    // Reset dma channel
    HW_APBH_CHANNEL_CTRL_SET(BF_APBH_CHANNEL_CTRL_RESET_CHANNEL(chipDmaMask));

    // Wait for the reset to complete
    while (HW_APBH_CHANNEL_CTRL.B.RESET_CHANNEL & chipDmaMask);

    // Clear IRQ
    HW_APBH_CTRL1_CLR(chipDmaMask);
}
