DTC Vector Base Register (DTCVBR)

Address(es): DTC.DTCVBR 0008 2404h
b31 b30
Value after reset: 0 0
b15 b14
Value after reset: 0 0
The DTCVBR register is used to set the base address for calculating the address to which the DTC vector is allocated.
Writing to the upper 4 bits (b31 to b28) is ignored, and the address of this register is extended by the value specified by
b27. The lower 10 bits are reserved and the values are fixed to 0. Write 0 to the lower 10 bits if necessary.
It can be set in the range of 0000 0000h to 07FF FC00h and F800 0000h to FFFF FC00h in 1-Kbyte units.

DTCADMOD register is used to specify the area accessible by the DTC.
SHORT Bit (Short-Address Mode Set)
This bit is used to select address mode of registers SAR and DAR.
Full-address mode allows the DTC to access to a 4-Gbyte space (0000 0000h to FFFF FFFFh).
Short-address mode allows the DTC to access to a 16-Mbyte space (0000 0000h to 007F FFFFh and FF80 0000h to
FFFF FFFFh).
