National is proud to present this software for programming all of National's RF wireless products. This is the software that can be used to program a PLL via the parallel port of a computer. Aside from this function, it is also a useful tool in addressing questions concerning how to program the part, because it shows the bits that are actually sent. This can also be useful in determining counter values and prescalers.
