GPIO can be configured for certain pins of the QSPI, DDR Control, timer, UART, Interrupt
and USB
interfaces. When in
GPIO mode, the timing specification for these pins is given in
Table 28
and
Figure 6
.
General Purpose I/O Timing
The GPIO timing is met under the following load test conditions:
50 pF / 50
Ω
for high drive
25 pF / 25
Ω
for low drive

All internal registers retain data at 0 Hz.

Depending on packaging; see

Loss of Reference Frequency is the reference frequency detected internally, which transitions the PLL into self clocked mode.
4
Self clocked mode frequency is the frequency at which the PLL operates when the reference frequency falls below f
LOR
with
default MFD/RFD settings.
5
This parameter is characterized before qualification rather than 100% tested.
6
Proper PC board layout procedures must be followed to achieve specifications.
7
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).
8
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 C
jitter
percentage
for a given interval.
