					GPIOF OR XF CPU OUTPUT SIGNAL
										This pin has three
										functions:
										1. XF –
										General-purpose
										output pin.
										2. XPLLDIS – This
										pin is sampled
										during reset to check
GPIOF14	XF_		(O)	137	153	42.6	4153.3	I/O/Z	PU	if the PLL needs to
		XPLLDIS								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.
										3. GPIO – GPIO
										function
