yep, can use X with a magic number
A non-blocking PULL on an empty FIFO has the same effect as MOV OSR, X. The program can either preload scratch register X with a suitable default, or execute a MOV X, OSR after each PULL NOBLOCK, so that the last valid FIFO word will be recycled until new data is available
