AC electrical characteristics

Notes: 1 ARM core and peripherals active with all clocks on. Power can be conserved by turning off

clocks to peripherals which are not required.

2 ARM core stopped and all peripheral clocks active.

3 ARM core stopped and all peripheral clocks stopped.

4 ARM core and all peripheral clocks stopped (with exception of RTC).
