- PIO_DONE_INTR: When PIO mode transfer finished, spi_intr_sts[2] will be high. Software write 1 to clean this bit.
- DMA_DONE_INTR: spi_intr_sts[1] indicate the current dma operation is done. Software can write 1 to clear this bit
- BUF_DATA_ENOU_INTR: spi_intr_sts[0] indicate the number of data received from flash has reached the setting amount. Software can write 1 to clear this bit. The amount is set in spi_cfg0[21] which is bit 21 of Group 87.6 register. Set spi_cfg0[21]=1, the buffer size is 32byte. Set spi_cfg0[21]=0, the buffer size is 64byte.
