; this routine is on page 0
; get the offset
; add the offset to PC
; the first byte is the byte count
; Initialize the PIC16Fxxx
; place the MCP2150 in reset
; Force the DTR pin high for program mode
; Force the RTS pin low for program mode
; delay for 1 ms.
; allow the MCP2150 to come out of reset
; LoopCnt = 0
; delay for 1 ms.
; if cts=0 then we're ready to program
; MCP2150 is ready to receive data
;
; NO, wait for MCP2150 to be ready
; The MCP2150 did not exit reset, do your recovery
