NormalOperation ; The MCP2150 in now programmed with new ID,
PIC16FXX Code to Program the Device ID (Continued)
; clear the offset
; get the byte count
;
; use creg as the loop counter
; add 1 to the loop count since
;
; save the count in areg to send it
; start sending the count + ID string
; get the byte
; save the byte
; check the cts input
; wait if cts=1
; send the byte using the Transmit Routine
; increment the table pointer
; more bytes to send?
; YES, send more bytes
; NO, place the MCP2150 in reset
; Force the DTR pin low for normal mode
; Force the RTS pin high for normal mode
; delay for 1 ms.
; allow the MCP2150 to come out of reset
; if cts=1 then MCP2150 is in Normal mode
; NO, wait for MCP2150 to be ready
; and is ready to establish an IR link
(ID length byte + # bytes in string)
