Bit 7—DTC Software Activation Enable (SWDTE): Enables or disables DTC activation by software.
When clearing the SWDTE bit to 0 by software, write 0 to SWDTE after reading SWDTE set to 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.
8.2.9
MSTPCR is a 16-bit readable/writable register that performs module stop mode control.
When the MSTP14 bit in MSTPCR is set to 1, the 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
21.5, 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.
Bit 14—Module Stop (MSTP14): Specifies the DTC module stop mode.
