Notes:
1. Perhipheral currents drop to zero when peripheral clock and peripheral are disabled, unless otherwise noted.
2. Currents are additive. For example, where
functions increases supply current by the specified amount.

3. ncludes all peripherals that cannot have clocks gated in the Clock Control module.
4. Includes supply current from internal regulator and PLL0OSC (>48 MHz), USB0OSC (48 MHz) or LPOSC0 (<48 MHz).
5. Flash execution numbers use 2 wait states for 80 MHz, 1 wait state for 48 MHz, and 0 wait states at 20 MHz or less.
6. RAM execution numbers use 0 wait states for all frequencies.
7. IDAC output current and IVC input current not included.
8. Bias current only. Does not include dynamic current from oscillator running at speed.
