236 / 1726 page ![]() Section 8 Data Transfer Controller (DTC) Rev. 1.00 Jun. 26, 2008 Page 206 of 1692 REJ09B0393-0100 8.2.7 DTC Enable Registers A to E (DTCERA to DTCERE) DTCER which is comprised of eight registers, DTCERA to DTCERE, is a register that specifies DTC activation interrupt sources. The correspondence between interrupt sources and DTCE bits is shown in table 8.2. Bit: Initial value: R/W: 15 14 13 12 11 10 987654321 0 0000000000000000 R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W DTCE15 DTCE14 DTCE13 DTCE12 DTCE11 DTCE10 DTCE9 DTCE8 DTCE7 DTCE6 DTCE5 DTCE4 DTCE3 DTCE2 DTCE1 DTCE0 Bit Bit Name Initial Value R/W Description 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 DTCE15 DTCE14 DTCE13 DTCE12 DTCE11 DTCE10 DTCE9 DTCE8 DTCE7 DTCE6 DTCE5 DTCE4 DTCE3 DTCE2 DTCE1 DTCE0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W DTC Activation Enable 15 to 0 Setting this bit to 1 specifies a relevant interrupt source to a DTC activation source. [Clearing conditions] • When writing 0 to the bit to be cleared after reading 1 • When the DISEL bit is 1 and the data transfer has ended • When the specified number of transfers have ended These bits are not cleared when the DISEL bit is 0 and the specified number of transfers have not ended [Setting condition] • Writing 1 to the bit after reading 0 |
