The below clock outputs are available on the processor for test and debug purposes only.
OBSCLK0, MCU_OBSCLK0 are observation clock outputs for test and debug purposes only. OBSCLK pins can be used to select one of the several different clocks as output. We do not expect this signal to be used as a clock source for any external device. As stated in the data sheet, this signal is provided for test and debug purposes only.
In case the processor pins designated OBSCLK0 (available on two pins in AM62x), OBSCLK0..1 (in AM62Ax and AM62Px), MCU_OBSCLK0, SYSCLKOUT0, MCU_SYSCLKOUT0 are not used, provide a test point for test or debug. Recommend adding pull resistors to these pads.
In case these pins are used, a test point can be inserted on the trace and provision to isolated these signals from the attached devices can be provided for test or debug.
System clock output pins (MCU_SYSCLKOUT0 and SYSCLKOUT0) are hardwired to dedicated clock resources.
