O
JTAG Test Data Output pin
JTAG_TMS
77
I
JTAG Test Mode Selector pin.
JTAG_TRST
81
I
JTAG Reset Pin. Both the boundary scan and ARM JTAG
uses this input for the JTAG clock.
ARM_JTAG_TDI
83
I
ARM JTAG Test Data Input pin
ARM_JTAG_TDO

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.

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.
