the signal with no fixed name is expressed by GPIO
4
、
The signal in the J9 interface has the potential to be multiplexed, does not
guarantee that the same time can provide the defined signal, use, please check
the schematic.
5. Table with * characters of CLK_P and CLK_N for CCM_CLK LVDS signal
。
6. The signal in the table with a character in the configuration of the GPIO, please
refer to the CPU manual on the introduction of the SNVS_TAMPER signal.
