Description
DTC Data Transfer Size
Specifies the size of data to be transferred.
0: Byte-size transfer
1: Word-size transfer
Description
DTC Chain Transfer Enable
This bit specifies a chain transfer. For details, see
section 8.5.4, Chain Transfer.
In data transfer with CHNE set to 1, determination of the
end of the specified number of transfers, clearing of the
interrupt source flag, and clearing of DTCER, are not
performed.
