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 H'0400 + (vector number) << 1 (where << 1 indicates a 1-bit left shift). For

example, if DTVEC6 to DTVEC0 = H'10, the vector address is H'0420.

MSTPCR, comprising two 8-bit readable/writable registers, 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. Note that 1 cannot be written to the MSTP14 bit

when the DTC is being activated. For details, see section 24.5, 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.

MSTPCRH Bit 6—Module Stop (MSTP14): Specifies the DTC module stop mode.
