Note:
no DC loads; outputs unloaded. All ports configured as inputs; measured with all modules enabled. PLL set to 240MHz out.
Operating Conditions: V
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 and time of day module operating.
3. Light Stop Mode - Operation frequency = 120 MHz, PLL set to 240 MHz, crystal oscillator and time of day module operating.
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
