1 _{The DMA module originally supported a left-justified 16-bit byte count register (BCR). This function was}
later reimplemented as a right-justified 24-bit BCR. The operation of the DMA and the interpretation of
the BCR is controlled by the MPARK[BCR24BIT]. See Chapter 8, “System Control Module (SCM)” for
more details.
2 _{UMR1n, UMR2n, and UCSRn should be changed only after the receiver/transmitter is issued a software}
reset command. That is, if channel operation is not disabled, undesirable results may occur.
