The guys from Arduino said the samd21 chip has its own oscillator to generate a 48MHz clock that is fed into the FPGA.
When i looked into the schematic of the vidor, i found that pin PA27 is connected to the FPGA pin E2 and it is labled SAM_PORTS.GCLK.
Is there a way to enable the clock on this pin in the samd21?
When i tried to use it for a clock divider that i programmed inside the FPGA, nothing happened.
