; File: BVECTORS.ASM -> Vector Table for the ‘C54x DSKplus
;
;
; ***************************************************************************
; 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.
;
;
; 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.

DO NOT MODIFY THESE FOUR VECTORS IF YOU PLAN TO USE THE DEBUGGER
———————mask and shift input data ——————————————

BSP vectors and Debugger vectors
TDM vectors just return
W
; load acc b with BSP buffer and shift right -0
; mask out the TRISTATE bits with #03FFFh
; invert the MSB for bipolar operation
; store B to out buffer and advance AR2 pointer
; output buffer is 2k starting at 1800h
; restart if out buffer is at 1fffh
;this is also a dummy return to define bsend
;in vector table file BVECTORS.ASM
;clear a chunk at the end to mark the end
U
;Set address of BSP buffer for clearing
;Set address of result for clearing
;The vectors start here
;initialize buffered serial port
;get BSP vectors
