5.3 Configure I/O Packet

The Configure I/O Packet configures the settings of a single I/O pin as part of the packet sequence. Unlike the Peripherals I/O table in the Input/Output Settings section, which displays all pins at once, this packet targets one pin at a time.

FieldDescription

DesignationThe function assigned to the pin (e.g., GPIO, CS0, CLKO, CTS)
DirectionInput or Output
OptionAdditional options for the pin; shows N/A when no options are available

  • Open-Drain is disabled when the direction is set to Input or when the designation is CLKO or CS0–CS3
