(1)

All inputs are tied to 0 V or to VCC. Outputs do not source or sink any current.

(2)

The currents are characterized with a Micro Crystal CC4V-T1A SMD crystal with a load capacitance of 9 pF.

(3)

Current for brownout and WDT clocked by SMCLK included.

(4)

Current for brownout and WDT clocked by ACLK included.

(5)

Current for brownout included.
