1.7.12. HPS UART Pins

Note: Altera recommends that you create an Quartus® Prime design, enter your device I/O assignments, and compile the design. The Quartus® Prime software will check your pin connections according to I/O assignment and placement rules. The rules differ from one device to another based on device density, package, I/O assignments, voltage assignments, and other factors that are not fully described in this document or the device user guides.
Table 33.  HPS UART PinsThere are two UART (UART0 and UART1) controllers for the Agilex™ 7 HPS.
