15.5.12MMC_I_REG Register (MMC_I_REG)

MMC_I_REG, shown in Table 15-16, shows the currently requested interrupt. The FIFO request interrupts, TXFIFO_WR_REQ, and RXFIFO_RD_REQ are masked off with the MMC_DMA_EN bit in the MMC_CMDAT register. The software is responsible for monitoring these bits in program I/O mode.

This is a read/write register. Ignore reads from reserved bits. Write zeros to reserved bits.
