Following are other methods to reduce power consumption further:
• The flash module may be powered down if code is run off SARAM. This results in a current reduction
of 18 mA (typical) in the V
DD
rail and 13 mA (typical) in the V
DDIO
rail.
• Savings in I
DDIO
may be realized by disabling the pullups on pins that assume an output function.
