IO pin named CLKOUT0 can be configured as clock output. The clock output can be used as clock source for the attached devices (Ex: Ethernet PHY).
It is possible to configure PADCONFIG53 and PADCONFIG157 for MUX MODE 5 at the same time, which will source CLKOUT0 to pins U13 and A19 at the same time. Each AM64x pin has its own IO buffer and the signal multiplexing is done on the processor side of the IO buffer. Therefore, should not encounter any signal integrity issues due to sourcing CLKOUT0 to both pins at the same time.
