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

Input. Must be permanently tied to VDD_IO or
GND.
SPI_SCLK
High impedance.
Driven, logic 0
Output. Output enable is R0x0032[13].
SPI_SDI
Internal pull-up enabled.
Internal pull-up enabled
Input. Internal pull-up is permanently enabled.
SPI_SDO
High impedance
Driven, logic 0
Output enable is R0x0032[13].
SPI_CS_N
High impedance
Driven, logic 1
Output enable is R0x0032[13].
FRAME_VALID
High impedance
High impedance
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.
LINE_VALID
PIXCLK
High impedance
Driven, logic 0
Output. This interface disabled by default.
