; mask with all Port0 bits
; compare to 0
; go to Port1 if not equal
; Read ICR0
; to make sure B1RIE is set
; if not, go to next interrupt
; P0PSR check
; D1 has the PLPSP0 value
; Go to read B1 if bit set
; Read ICR0 to make sure B1TIE
; is set
; B1TDE Test
; go to Transmit B1 if bit set
; Read ICR0 to make sure B2RIE
; is set
; R2RDF Test
; Go to read B2 if bit set
; B2TDE Test
; go to Transmit B2 if bit set
; Read ICR0 to make sure DRIE
; is set
; if not, go to next source
; DRIE is set, needs to
; receive the D data
; Go to Read D if bit set
; Read ICR0(DTIE) to make
; sure the bit is set
; go to next port
; DTDE Test
; IE Test on Port1
