  • Added information for MAX 10 devices.
  • Added support for MAX V devices.
  • Added missing link to download the design example file for MAX V, MAX II, and MAX 3000A device families.
  • Added link to download the design example file for MAX 10 devices.
  • Removed tables that list the MultiVolt I/O support and number of maximum user I/O pins for the MAX II and MAX 3000A devices, and added links to related device-specific documents that list the information. The linked documents provide more details and contain the latest information for each device family.
  • Changed the figure that shows the I/O expander address bus configuration into a table for easier reference.
  • Removed the table that lists the port addresses configuration values and combined the information in the table that lists the I/O expander address bus configuration details.
  • Added a table that lists the design example target devices and combined the resource utilization information into this table for easy reference.
  • Updated the microcontroller I/O expander read and write timing simulation figures.
  • Restructured and rewrote all sections for clarity and style update.
  • Updated template.
