* negative edge BCLKR
* negative BFSR pulse
* no data shifted
* 1’ cable from counter to CONV at DUT
* 2’ cable from counter to CLK at DUT
*No right shift is needed to right justify the input data in the main program
*the two msbs should also be masked....................

; places buffered serial port in reset
; clear interrupt fl ags
; Enable HPINT,enable BRINT0
; all unmasked interrupts are enabled.
; programs BSPCE and ABU
; initializes transmit buffer start address
; initializes transmit buffer size
; initializes receive buffer start address
; initializes receive buffer size
; bring buffered serial port out of reset
;for transmit and receive because GO=0xC0
