J970 connector
J970 is used to implement a keypad, it is connected to TPS65950. The keypad interface controller provides an enhanced keypad decode capability and simultaneously reduces host processor software overhead. More information in TPS65950 datasheets. TPS65950 send via I2C1 all the interrupt request. Their characteristics are:
