NOTES:

Supply current does not include current drawn through internal pull-up resistors, LCD voltage dividing resistors, and

ADC.

IDD1 and IDD2 include power consumption for subsystem clock oscillation.

IDD3 and IDD4 are current when main system clock oscillation stops and the subsystem clock is used.

IDD5 is current when main system clock and subsystem clock oscillation stops.
