2.2.3.1 176-Pin PTP Pins with Different GPIO Assignment

Table 2-3 176-P PTP Legend
Color Description
common for both devices
applicable only for F2837x
applicable only for F28P65x
Note: For the mux table below, there would be instances where SPI pins will show differences, but this will be only with the name. Functionality will be the same. Name change in F28P65x are as follows:
  • SPI_SOMI to SPI_POCI
  • SPI_SIMO to SPI_PICO
  • SPI_STE to SPI_PTE
