BSP vectors and Debugger vectors

;

TDM vectors just return

; ***************************************************************************

; The vectors in this table can be configured for processing external and

; internal software interrupts. The DSKplus debugger uses four interrupt

; vectors. These are RESET, TRAP2, INT2, and HPIINT.

;

* DO NOT MODIFY THESE FOUR VECTORS IF YOU PLAN TO USE THE DEBUGGER *

;

; All other vector locations are free to use. When programming always be sure

; the HPIINT bit is unmasked (IMR=200h) to allow the communications kernel and

; host PC interact. INT2 should normally be masked (IMR(bit 2) = 0) so that the

; DSP will not interrupt itself during a HINT. HINT is tied to INT2 externally.
