All values are measured with a 3.30V EV
supplies. Tests performed at room temperature with pins configured for high drive
strength.
CPU polling a status register. All peripheral clocks except UART0, FlexBus, INTC,
reset controller, PLL, and edge port disabled.
Peak current measured while running a while(1) loop with all modules active.
