(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. The internal and external

load capacitance are chosen to closely match the required 9 pF.

(3)

Current for brownout and WDT clocked by SMCLK included.

(4)

Current for brownout, WDT and RTC clocked by ACLK included.

(5)

Current for brownout, WDT and RTC clocked by ACLK included.
