The processor retains the state of each I/O port even when it goes to wait mode or to stop mode. A
current flows in active I/O ports. A dash current may flow through the input ports in high impedance
state, if the input is floating. When entering wait mode or stop mode, set non-used ports to input and
stabilize the potential.
When A/D conversion is not performed, set the VCUT bit in ADCON1 register to “0” (no Vref connec-
tion). When A/D conversion is performed, start the A/D conversion at least 1 s or longer after setting
the VCUT bit to “1” (Vref connection).
Use the CM0 register CM02 bit to stop the unnecessary peripheral functions during wait mode.

Set the driving capacity to “LOW” when oscillation is stable.
