bufull:
b = *ar3+ << -0 ; load acc b with BSP buffer and shift right -0
b = #07FFFh & b ; mask out the TRISTATE bits with #03FFFh
;
*ar2+ = data(#0bh) ; store B to out buffer and advance AR2 pointer
TC = (@ar2 == #02000h) ; output buffer is 2k starting at 1800h
if (TC) goto start ; restart if out buffer is at 1fffh

; 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.
