DESCRIPTION
GPIOF OR XF CPU OUTPUT SIGNAL
GPIOF14
XF_XPLLDIS (O)

I/O/Z
PU
This pin has three functions:
1. XF
General-purpose output pin.
2. XPLLDIS
This pin will be sampled
during reset to check if the PLL needs
to be disabled. The PLL will be
disabled if this pin is sensed low. HALT
and STANDBY modes cannot be used
when the PLL is disabled.

Typical drive strength of the output buffer for all pins [except TDO, XCLKOUT, XF, XINTF, EMU0, and EMU1 pins] is 4 mA typical.
I = Input, O = Output, Z = High impedance
§
PU = pin has internal pullup; PD = pin has internal pulldown
NOTE:
Other than the power supply pins, no pin should be driven before the 3.3-V rail has reached
recommended operating conditions. However, it is acceptable for an I/O pin to ramp along with
the 3.3-V supply.
