(6) Exception/debug trap status saving registers (DBPC and DBPSW)
(7) CALLT base pointer (CTBP)
DBPSW
CTBP
DBPC
DBPC and DBPSW are exception/debug trap status registers.
If an exception trap or debug trap occurs, the contents of the program counter (PC) are saved to DBPC, and
those of the program status word (PSW) are saved to DBPSW.
The contents to be saved to DBPC are the address of the instruction next to the one that is being executed
when an exception trap or debug trap occurs.
The current contents of the PSW are saved to DBPSW.
This register can be read or written only during the interval between the execution of the DBTRAP instruction
or illegal opcode and the DBRET instruction.
Bits 31 to 26 of DBPC and bits 31 to 8 of DBPSW are reserved for future function expansion (fixed to 0).
The value of DBPC is restored to the PC and the value of DBPSW to the PSW by the DBRET instruction.
The CALLT base pointer (CTBP) is used to specify a table address or generate a target address (bit 0 is fixed
to 0).
Bits 31 to 26 of this register are reserved for future function expansion (fixed to 0).
