A DTCE bit can be set for each interrupt source that can activate the DTC. The correspondence
between interrupt sources and DTCE bits is shown in table 7.5, together with the vector numbers
generated by the interrupt controller.
For DTCE bit setting, read/write operations must be performed using bit-manipulation instructions
such as BSET and BCLR. For the initial setting only, however, when multiple activation sources
are set at one time, it is possible to disable interrupts and write after executing a dummy read on
the relevant register.
7.2.8
DTVECR is an 8-bit readable/writable register that enables or disables DTC activation by
software, and sets a vector number for the software activation interrupt.
DTVECR is initialized to H'00 by a reset and in hardware standby mode.
Note: * Bits DTVEC6 to DTVEC0 can be written to when SWDTE = 0.
