OMAP L138 GP8 Registers

TMS320C674x/OMAP-L1x Processor General-Purpose Input/Output (GPIO) (SPRUFL8A) does not mention GP8 or any registers related to it.  However, the datasheet and TRM do reference GP8.  Where is the direction register for GP8 documented?

  • Inderjit,

    The manual is intended to be open-ended in its register definitions.  The number of supported GPIO pins varies from device-to-device, but the base GPIO module is often the same with the registers and field definitions enumerated in a well-defined pattern.  There are notes in the manual that indicate that the user can assume the pattern continues if more pins are supported and that registers/fields are reserved for devices with fewer pins.  For the sake of documenting the superset pincount for the OMAPL1x/C674x family, the userguide is being updated with GPIO8 register and field information.  It should be on the external web in a day or two.
