  Applications  　PSM(Pin),JS(Jumper)  ●Circuit switching

The use of pins and jumpers enables the changing and switching of
circuit settings and the upgrading of CPU clock counts. Pins and
jumpers can also function as circuit terminals for reset switches.
(Square pin specifi cation pin headers only.)
