Deletion of subsystem clock oscillator feedback resistor
possible
Note 1. In a system not using subsystem clocks, power consumption in the STOP mode can be decreased by
removing the feedback resistor from the oscillator.
2. The feedback resistor must be incorporated when using subsystem clock.
(2) Power-on reset generator, power-on flag (PONF)
One of the following three can be selected.
