Ports: I/O ports maintains the same state despite the microcomputer entering wait mode or stop
mode. Current flows through active output ports. Feedthrough current flows through input ports in a
high-impedance state. Set unassigned ports as input ports and stabilize electrical potential before
entering wait mode or stop mode.
A/D Converter: If the A/D conversion is not performed, set the VCUT bit in the AD0CON1 register
to "0" (no V
starting the A/D conversion.
D/A Converter: Set the DAi bit (i=0, 1) in the DACON register to "0" (output disabled) and set the
DAi register to "00
Peripheral Function Stop: Set the CM02 bit in the CM0 register while in wait mode to stop unnec-
essary peripheral functions. However, this does not reduce power consumption because the pe-
ripheral function clock (fc32) generating from the sub clock does not stop. When in low-speed mode
and low-power consumption mode, do not enter wait mode when the CM02 bit is set to "1" (periph-
eral clock stops in wait mode).
