Hi, Vybrid expert
in Vybrid_1N02G, we descript 7293 as follows:
e7293: XTAL: ROM code may fail to boot and return to safe mode due to insufficient
warm up time for the crystal oscillator
Errata type: Errata
Description: On occasion the xtal oscillator may not get sufficient time to stabilize. In this case, the boot
code will jump to safe mode and will continue to operate from the internal RC clock.
Workaround: Use an external clock/oscillator module to clock to the processor, ensuring the clock signal is
stable no more than 1.2 msecs after reset is released.
so my question is:
can I understand this errata that customer MUST add a external clock/oscillator if they want to be safe ( I think it's a normal requirment)?
