This entry point has no effect if logging has not been compiled into the usb8x binary. Each log entry is four bytes long and there is no bound checking. Make sure your log buffer wont overflow or the calculator will most likely crash. Make sure to call [[../DriverInit|DriverInit]] before calling SetupLog.

Example

       U_CALL DriverInit
       ld     hl,8000h
       ld     b,82h
       U_CALL SetupLog
