Clocking issue - 4245AXI
I'm having an issue where the set clock on one of my 4245AXI in 44TQFP does not match the actual clock. When the system clock is set to 48MHz and a pin set to generate a 1MHz clock, the micro only generates a 290KHz clock. When the system clock is set to 14MHz, a 973KHz clock is generated and when system clock is set to 5MHz a 2.69MHz signal is generated. So it seems the internal main oscillator is stuck at 13.5MHz.
When I run the same code on another 4245AXI on cy8ckit dev board, it generates 1MHz no issue. So I believe the microcontroller hardware is faulty.
The problematic microcontoller is on a PCB I designed, I was wondering if this was a common issue?
