Need help in the Interrupt implementation for SDMMC driver.
I enabled the interrupt in the control register in the function: sdio_init as:LPC_SDMMC->CTRL = MCI_CTRL_USE_INT_DMAC | MCI_CTRL_INT_ENABLE;
anf i enabled the LPC_SDMMC->RINTSTS = 0xFFFFFFCE;(which implies Rx,TX Interrupt and CDET(card detect)). and i masked the below register. (// LPC_SDMMC->TMOUT = 0xFFFFFFFF;).
but i didnt got any Interrupt. in SDIO_IRQHandler. i added few the status checking for the above 3 functionalities.
I am having small doudt like MCI_CTRL_USE_INT_DMAC is the internal DMA so need to enable in the internal DMA registers.
Please suggest the right way.
Thanks & Regards,
