7.3.7 GPIO Supported Functionality

The DLPC23xS-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.

(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.
