I've been scanning through the Cypress PSOC4200L Datasheet and USBFS Documents,
but I am not sure if an external cyrstal is required for USB Full Speed Application with the PSOC4200L?
Does anybody know?
Welcome in the forum, Julian.
To maintain 0.25% accuracy required for USBFS you will need to trim the IMO using the optoin "to USB"
use an external crystal, either a 24MHz or a 32kHz watch crystal.
