1.3 LVCMOS IO

This section allows you to select both Mode and Utilization of a subset of commonly used IO’s on the AM64x/AM243x, including UART (3.3 V), SPI (3.3 V), Ethernet (3.3 V), OSPI (1.8 V), and GPMC (3.3 V).

Note: This is not the complete set of IO’s possible on the AM64x/AM243x, and any IO configuration must be confirmed through the AM64x or AM243x pinmux tool. These are dual voltage IO domains (1.8 V or 3.3 V), but currently are fixed to match the EVM design.
  • Mode: IO dependent mode and operating speed.
  • Utilization (%): Specifies the utilization as a percentage of activity relative to a full load condition.
  • For AM243 ALX device, use the settings in the following table.

OSPI Only QSPI selections valid
GPMC OFF 0%
