Section 8 Data Transfer Controller (DTC)
Bit 7—DTC Software Activation Enable (SWDTE): Enables or disables DTC activation by
software.
Bit 7
SWDTE
0
1
Bits 6 to 0—DTC Software Activation Vectors 6 to 0 (DTVEC6 to DTVEC0): These bits
specify a vector number for DTC software activation.
The vector address is expressed as H'0400 + ((vector number) << 1). <<1 indicates a one-bit left-
shift. For example, when DTVEC6 to DTVEC0 = H'10, the vector address is H'0420.
