A. INT[1:0] can only be used as a wake-up event for IDLE3 and IDLE2 modes.
B. RTC interrupt (internal signal) can be used as wake-up event for IDLE3 and IDLE2 modes.
C. Any unmasked interrupt can be used to exit the IDLE2 mode.
D. CLKOUT reflects either the CPU clock, SAR, USB PHY, or PLL clock dependent on the setting of the CLOCKOUT
Clock Source Register. For this diagram, CLKOUT refers to the CPU clock.

(1) P = 1/SYSCLK clock frequency in ns. For example, when the CPU core is clocked at 100 MHz, use P = 10 ns.
(2) C = 1/RTCCLK= 30.5 μs. RTCCLK is the clock output of the 32.768-kHz RTC oscillator.
