Notes: 1. For the NMIF and AE bits, only a 0 write after a 1 read is possible.
8.2.9
The DTBR is a 16-bit readable/writable register that specifies the upper 16 bits of the memory
address containing DTC transfer information. Always access the DTBR in word or longword
units. If it is accessed in byte units the register contents will become undefined at the time of a
write, and undefined values will be read out upon reads.
The initial value of DTBR is undefined.

Description
DTC Software Activation Vectors 7 to 0
These bits specify the lower eight bits of the vector
addresses for DTC activation by software.
A vector address is calculated as H'0400 + DTVEC
(7:0). Always specify 0 for DTVEC0. For example,
when DTVEC7 to DTVEC0 = H'10, the vector
address is H'0410. When the bit SWDTE is 0, these
bits can be written to.
