General Purpose I/O Timing
GPIO can be configured for certain pins of the QSPI, DDR Control, TIMERS, UARTS, FEC0, FEC1,
Interrupts and USB interfaces. When in GPIO mode, the timing specification for these pins is given in
Table 26
and

NOTES:
1
All internal registers retain data at 0 Hz.
2
“Loss of Reference Frequency” is the reference frequency detected internally, which transitions the PLL into self
clocked mode.
3
Self clocked mode frequency is the frequency that the PLL operates at when the reference frequency falls below
f
LOR
with default MFD/RFD settings.
4
This parameter is characterized before qualification rather than 100% tested.
5
Proper PC board layout procedures must be followed to achieve specifications.
6
This specification applies to the period required for the PLL to relock after changing the MFD frequency control bits
in the synthesizer control register (SYNCR).
7
Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum
f
sys
. 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
DDPLL
and V
SSPLL
and variation in crystal oscillator frequency
increase the Cjitter percentage for a given interval
