converter (table 9.4). When this mode is selected, if DMA transfer is enabled (DE = 1, DME = 1,
TE = 0, NMIF = 0, AE = 0), a transfer is performed upon input of a transfer request signal. The
source of the transfer request does not have to be the data transfer source or destination. When
RXI is set as the transfer request, however, the transfer source must be the SCI’s receive data
register (RDR). Likewise, when TXI is set as the transfer request, the transfer source must be the
SCI’s transmit data register (TDR). If the transfer request is from the A/D converter, the data
transfer source must be an A/D converter register.
