Section 7 Data Transfer Controller
Bit 7—DTC Software Activation Enable (SWDTE): Enables or disables DTC activation by
software.

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.
7.2.9
MSTPCR is a 16-bit readable/writable register that performs module stop mode control.
When the MSTP14 bit in MSTPCR is set to 1, DTC operation stops at the end of the bus cycle and
a transition is made to module stop mode. However, 1 cannot be written in the MSTP14 bit while
the DTC is operating. For details, see section 19.5, Module Stop Mode.
MSTPCR is initialized to H'3FFF by a reset and in hardware standby mode. It is not initialized in
software standby mode.
