Crystal Oscillator Output — This output connects the
internal crystal oscillator output to an external crystal.
If an external clock is used, XTAL must be used as the input
and EXTAL connected to GND.
The input clock can be selected to provide the clock directly
to the core. This input clock can also be selected as the input
clock for the on-chip PLL.

disabled
Clock Output — This pin outputs a buffered clock signal.
Using the SIM CLKO Select Register (SIM_CLKOSR), this
pin can be programmed as any of the following: disabled,
CLK_MSTR (system clock), IPBus clock, oscillator output,
prescaler clock and postscaler clock. Other signals are also
available for test purposes.
See Part 6.5.7 for details.

Address Bus — A0 - A5 specify six of the address lines for
external program or data memory accesses.
Depending upon the state of the DRV bit in the EMI bus
control register (BCR), A0 - A5 and EMI control signals are
tri-stated when the external bus is inactive.
Most designs will want to change the DRV state to DRV = 1
instead of using the default setting.
Port A GPIO — These six GPIO pins can be individually
programmed as input or output pins.
After reset, the default state is Address Bus.
To deactivate the internal pull-up resistor, clear the
appropriate GPIO bit in the GPIOA_PUR register.
Example: GPIOA8, clear bit 8 in the GPIOA_PUR register.
