GPIO can be configured for certain pins of the QSPI, timers, UARTs, FEC, and interrupts. When in GPIO mode, the timing
specification for these pins is given in
The GPIO timing is met under the following load test conditions:
Freescale Semiconductor
This value has been updated
Load capacitance determined from crystal manufacturer specifications and include circuit board parasitics.
Assuming a reference is available at power up, lock time is measured from the time V
negating. If the crystal oscillator is the reference for the PLL, the crystal start up time must be added to the PLL lock time to
determine the total start-up time.
Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum f
Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal. Noise
injected into the PLL circuitry via V
for a given interval
Based on slow system clock of 40 MHz measured at f
