8.2.9
DTCVBR is a 32-bit register that specifies the base address for vector table address calculation.
8.2.10
BSCEHR is a 16-bit register that specifies the timing of bus release by the DTC and other
functions. This register can be used to give higher priority to the transfer by the DTC and
configure the functions that can reduce the number of cycles over which the DTC is active. For
more details, see section 9.4.4, Bus Function Extending Register (BSCEHR).
