5.7 GPIO Peripheral Interface

PIN(1) I/O TYPE(3) DESCRIPTION(2)
NAME NO.
GPIO_19 M15 I/O 1 General purpose I/O 19 (hysteresis buffer). Optional GPIO. If unused, TI recommends this pin be configured as a logic zero GPIO output and left unconnected. Otherwise this pin requires an external pullup or pulldown to avoid a floating GPIO input.
GPIO_18 M14 I/O 1 General purpose I/O 18 (hysteresis buffer). Options:
  1. Optional GPIO. If unused, TI recommends this pin be configured as a logic zero GPIO output and left unconnected. Otherwise this pin requires an external pullup or pulldown to avoid a floating GPIO input.
  2. MTR_SENSE, Motor Sense (Input): For focus motor control applications, this GPIO must be configured as an input to the DLPC34xx and supplied from the focus motor position sensor.
GPIO_17 L15 I/O 1 General purpose I/O 17 (hysteresis buffer). Optional GPIO. If unused, TI recommends this pin be configured as a logic zero GPIO output and left unconnected. Otherwise this pin requires an external pullup or pulldown to avoid a floating GPIO input.
GPIO_16 L14 I/O 1 General purpose I/O 16 (hysteresis buffer). Optional GPIO. If unused, TI recommends this pin be configured as a logic zero GPIO output and left unconnected. Otherwise this pin requires an external pullup or pulldown to avoid a floating GPIO input.
GPIO_15 K15 I/O 1 General purpose I/O 15 (hysteresis buffer). Optional GPIO. If unused, TI recommends this pin be configured as a logic zero GPIO output and left unconnected. Otherwise this pin requires an external pullup or pulldown to avoid a floating GPIO input.
GPIO_14 K14 I/O 1 General purpose I/O 14 (hysteresis buffer). Optional GPIO. If unused, TI recommends this pin be configured as a logic zero GPIO output and left unconnected. Otherwise this pin requires an external pullup or pulldown to avoid a floating GPIO input.
GPIO_13 J15 I/O 1 General purpose I/O 13 (hysteresis buffer). Optional GPIO. If unused, TI recommends this pin be configured as a logic zero GPIO output and left unconnected. Otherwise this pin requires an external pullup or pulldown to avoid a floating GPIO input.
GPIO_12 J14 I/O 1 General purpose I/O 12 (hysteresis buffer). Optional GPIO. If unused, TI recommends this pin be configured as a logic zero GPIO output and left unconnected. Otherwise this pin requires an external pullup or pulldown to avoid a floating GPIO input.
GPIO_11 H15 I/O 1 General purpose I/O 11 (hysteresis buffer). Options:
  1. Thermistor power enable (output). Turns on the power to the thermistor when it is used and enabled.
  2. Optional GPIO. If unused, TI recommends this pin be configured as a logic zero GPIO output and left unconnected. Otherwise this pin requires an external pullup or pulldown to avoid a floating GPIO input.
GPIO_10 H14 I/O 1 General purpose I/O 10 (hysteresis buffer). Options:
  1. RC_CHARGE (output): Intended to feed the RC charge circuit of the thermistor interface.
