Pin Assignments
Pin 1 is not populated with a ball. That allows the device
to be identified by an additional marking.

Notes
Input
Input
Input
Input. Must always be driven to high via
a pull-up resistor in the range of 1.5 to 4.7 kΩ.
Input/Output. Must always be driven to high via
a pull-up resistor in the range of 1.5 to 4.7 kΩ.
Input. Must be permanently tied to VDD_IO or
GND.
Output. Output enable is R0x0032[13].
Input. Internal pull-up is permanently enabled.
Output enable is R0x0032[13].
Output enable is R0x0032[13].
Input/Output. This interface is disabled by
default. Input buffers (used for GPIO function)
powered down by default, so these pins can be
left unconnected (floating). After reset, these
pins are powered up, sampled, then powered
down again as part of the auto-configuration
mechanism. See Note 2.
Output. This interface disabled by default.
See Note 1.
