From the datasheet, I can generate 180M system clock from FRO_12M clock or CLK_IN(see attached).
but in datasheet page 53 table 5(attached below), says:
|XTALIN||-||Connect to ground. When grounded, the RTC oscillator is disabled.|
Does this mean, I can't run 5460x with out oscillator input? I just want to simplify the design.
