The followings are suggestions to reduce power consumption when programming or designing systems.

Through current may flow into floating input pins. Set unassigned pins to input mode and connect them to
VSS via a resistor (pull down), or set unassigned pins to output mode and leave them open.
When the A/D conversion is not performed, set the VCUT bit in the AD0CON1 register to 0 (VREF not
connected). When the A/D conversion is performed, set the VCUT bit to 1 (VREF connection) and wait
1 μs or more to start the A/D conversion.
When the D/A conversion is not performed, set the DAiE bit (i = 0, 1) in the DACON register to 0 (output
disabled) and registers DACON1 and DAi to 00h.
When entering wait mode from main clock mode, on-chip oscillator mode, or on-chip oscillator low-power
consumption mode, power consumption can be reduced by setting the CM02 bit in the CM0 register to 1 to
stop peripheral function clock source (fPFC). However, fC32 does not stop by setting the CM02 bit to 1.
In low-speed mode, do not set the CM02 bit to 1 (peripheral clock stops in wait mode) when entering wait
mode.
