INITIALIZATION AND PROGRAMMING EXAMPLES
* In the second demo, the PAI pin should be connected
Freescale Semiconductor, Inc.
The 1st demo requires that the pins OC2, IC1, IC2,
and IC3 be tied together so that OC2 may drive
IC1, IC2, & IC3.
to the PWMA pin.
will ring when the Pulse Accumulator Counter
For More Information On This Product,
;space for delay counter
;increment IX to point to the next byte
;loop back and do next byte in string
;subroutine to implement delay between messages
;load accumulator E with the delay time
;set up the counter
;decrement the counter
;count down to zero
;finish delay loop go back to main
;subroutine to send out one byte to SCI
;read SCI status reg to check/clear TDRE bit
;check only the TDRE flag bit
;if TDR is not empty, go back to check it again
;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
;exception vectors point here
;and put the user in background debug mode
;start of 1K internal SRAM for data & stack
