Re: read security bits

Hello, in the XE216-512-TQ128 Datasheet is written: If bit 5 of the security register (see §9.1) is set, the device boots from OTP. To get a high value, a 3K3 pull-up resistor should be strapped onto the pin. To assure a low value, a pull-down resistor is required if other external devices are conne...

Re: USB doesn't enumerate in xCORE-200 Multichannel Audio Platform

Hello mon2, this afternoon I'll try what you are suggesting. In any case I didn't place any required inrush current protection onto Vbus of the XMOS device because I didn't change anything in the xCORE-200 Multichannel Audio Platform I received XMOS via distributor.
