Since the code must be inserted in the middle of the module, it's split out into this file and #included. Jump destinations called from outside: sofError: Called when no start sequence was found. se0: Called when a package has been successfully received. overflow: Called when receive buffer overflows. doReturn: Called after sending data. Outside jump destinations used by this module: waitForJ: Called to receive an already arriving packet. sendAckAndReti: sendNakAndReti: sendCntAndReti: usbSendAndReti: The following macros must be defined before this file is included: .macro POP_STANDARD .endm .macro POP_RETI .endm */ #define token x1 overflow: ldi x2, 1<
