1. Running Core, performing 50% NOP and 50% FIR. Clock at 120 MHz.
2. Deep Stop Mode - Operation frequency = 4 MHz, PLL set to 4 MHz, crystal oscillator.
3. Light Stop Mode - Operation frequency = 120 MHz, PLL set to 240 MHz, crystal oscillator.
4. I
5. Running core and performing external memory access. Clock at 120 MHz.
6. When V
7. Power-on reset occurs whenever the digital supply drops below 1.8V. While power is ramping up, this signal remains active
as long as the internal 2.5V is below 1.8V, no matter how long the ramp up rate is. The internally regulated voltage is typically
100mV less than V
