I/O Description
I JTAG Clock pin. Both the boundary scan and ARM JTAG
uses this input for the JTAG clock.
I JTAG Test Data Input pin
O JTAG Test Data Output pin
I JTAG Test Mode Selector pin.
I JTAG Reset Pin. Both the boundary scan and ARM JTAG
uses this input for the JTAG clock.
I ARM JTAG Test Data Input pin
O ARM JTAG Test Data Output pin
I ARM JTAG Test Mode Selector pin

I/O I C Clock Pin. This pin should be tied to ground if no EEPOM
is used.
For EEPROM write operations, the GPIO8 settings are muxed
with the SCL pin. Software can manipulate the GPIO8
register settings in order to perform a write.

I/O I C Data Pin
For EEPROM write operations, the GPIO9 settings are muxed
with the SDA pin. Software can manipulate the GPIO9
register settings in order to perform a write.
I/O GPIO0. Can be programmed as general-purpose input,
general-purpose output, or specific function. Power-up default
is input.
I/O GPIO1. Can be programmed as general-purpose input,
general-purpose output, or specific function. Power-up default
is input.
I/O GPIO2. Can be programmed as general-purpose input,
general-purpose output, or specific function. Power-up default
is input.
I/O GPIO3. Can be programmed as general-purpose input,
general-purpose output, or specific function. Power-up default
is input.
I/O GPIO 4. Can be programmed as general-purpose input,
general-purpose output, or specific function. Power-up default
is input.
I/O GPIO 5. Can be programmed as general-purpose input,
general-purpose output, or specific function. Power-up default
is input.
I/O GPIO6. Can be programmed as general-purpose input,
general-purpose output, or specific function. Power-up default
is input.
I/O GPIO7. Can be programmed as general-purpose input,
