5.7 GPIO Peripheral Interface

PIN(1)I/OTYPE(3)DESCRIPTION(2)
NAMENO.
GPIO_19M15I/O1General 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_18M14I/O1General 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_17L15I/O1General 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_16L14I/O1General 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_15K15I/O1General 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_14K14I/O1General 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_13J15I/O1General 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_12J14I/O1General 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_11H15I/O1General 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_10H14I/O1General Purpose I/O 10 (hysteresis buffer). Options:
  1. RC_CHARGE (output): Intended to feed the RC charge circuit of the thermistor interface.
  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_08G14I/O1General purpose I/O 08 (hysteresis buffer). Normal mirror parking request (active low): To be driven by the PROJ_ON output of the host. A logic low on this signal causes the DLPC34xx to PARK the DMD, but it does not power down the DMD (the DLPAxxxx does that instead). At power-up, GPIO_08 must remain high until HOST_IRQ goes low (see Section 9.3).
GPIO_07F15I/O1General purpose I/O 07 (hysteresis buffer). 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. Optional DSI Bus Width Config 1 (input): The controller samples this pin during boot and is used to define the number of lanes used for DSI operation. Requires an external pullup or pulldown resistor to configure as defined in Table 5-1. After boot, this GPIO pin will continue to be used as SPI1_DOUT. Select the external pullup or pulldown resistor to not interfere.

(1) GPIO pins must be configured through software for input, output, bidirectional, or open-drain operation. Some GPIO pins have one or more alternative use modes, which are also software configurable. An external pullup resistor is required for each signal configured as open-drain.
(2) General purpose I/O for the DLPC3430 and DLPC3435 controllers. These GPIO pins are software configurable.
