other internal blocks.
Use OP1 and OP2 to switch among different operation
mode (NORMAL, SLOW, IDEL and SLEEP). In Dual
Clock mode, the main system clock is still the Fast
Clock. The 32768Hz clock is for LCD and Timer 1 only.
Level trigger, active low. Except for using this pin, using
mask option (MO_PORE=1) could enable IC build-in
