;check only the TDRE flag bit
;if TDR is not empty, go back to check it
;clear A to send a full word to SCDR ($FFC0E)
;transmit one ASCII character to the screen
;test the TC bit (transfer complete)
;continue to wait until TC is set
;finish sending out byte
;execute when IC1 senses a transition
;print the message
;clear the IC1 flag bit
;execute when IC2 senses a rising edge
;print the message
;clear the IC2 flag bit
;execute when IC3 senses a falling edge
