MIC input DMA data (from MIDATREG to buffer)
This register is used prior to DMA transfer to store 10-bit data that has been converted by the A/D converter and
stored in MIDATREG. Write is used for debugging and is enabled when AIUMEN bit of SEQREG is set to 1. This
register is cleared (0x0200) by resetting AIUMEN bit of SEQREG to 0.
