(SRAM)
1
Tested at room temperature with CPU polling a status register. All clocks were off except the UART and CFM (when
running from flash memory).
2
Peak current measured with all modules active, CPU polling a status register, and default drive strength with matching
load.
3
Tested using Auto Power Down (APD), which powers down the ADC between conversions; ADC running at 4 MHz in
Once Parallel mode with a sample rate of 3 kHz.
4
Tested with the PLL MFD set to 7 (max value). Setting the MFD to a lower value results in lower current consumption.
