7.3.7 GPIO Supported Functionality

The DLPC23x-Q1 provides 32 general purpose I/O that are available to support a variety of functions for a number of different product configurations. In general, most of these I/O will only support one specific function based on a specific product configuration, although that function can be different for a different product configuration. There are also a few of these I/O that have been reserved for use by the Host for whatever function they can require. In addition, most of these I/O can also be made available for TI test and debug use. Definitions for the HUD and Headlight product configurations are shown in Table 7-7 and Table 7-8.

Table 7-7 GPIO Supported Functionality - HUD Product Configuration
GPIOSIGNAL NAMEDESCRIPTION (1)
GPIO_00PMIC_CNTRL_OUT (input)LED control feedback from the TPS99000-Q1. An external pulldown resistor must be used (connects to TPS99000-Q1 Drive Enable).
GPIO_01PMIC_SEQ_STRT (output)Sequence start output from the DLPC23x-Q1. This must be connected to the TPS99000-Q1 to time LED related actions and shadow TPS99000-Q1 configuration registers. An external pulldown resistor must be used.
GPIO_02PMIC_COMP_OUT (input)LED optical comparison feedback. This is used to count light pulses during each frame. This signal is active-low. An external pulldown resistor must be used.
GPIO_03PMIC_LED_SEN (output)LED Shunt Enable - shunts current from LEDs to allow faster LED turn-off. An external pulldown resistor must be used.
GPIO_04PMIC_LED_DEN (output)LED FET Drive Enable - enables LED current switching and defines LED pulse length. An external pulldown resistor must be used.
GPIO_05Reserved for Future UseAn external pulldown resistor must be used

GPIO_15PMIC_WD1 (output)Periodic signal that the DLPC23x-Q1 processor generates during normal operation. TPS99000-Q1 monitors this signal and reports if this signal stops pulsing. An external pulldown resistor must be used.

(1) TI recommends that all unused Host Available GPIO be configured as a logic '0' output and be left unconnected in the system. If this is not done, an external pulldown resistor (≤ 10 kΩ) must be used to avoid floating inputs.
