GPIOF OR XF CPU OUTPUT SIGNAL

GPIOF14 -

XF_XPLLDIS (O)

A11

101

I/O

This pin has three functions:

XF – General-purpose output pin.

XPLLDIS – This pin is sampled during

reset to check whether the PLL must 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.

GPIO – GPIO function

GPIOG OR SCI-B SIGNALS

GPIOG4 - SCITXDB (O)

P14

I/O/Z

–

GPIO or SCI asynchronous serial port transmit

data

GPIOG5 - SCIRXDB (I)

M13

I/O/Z

–

GPIO or SCI asynchronous serial port receive

data

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.
