7.6 USB
PSoC includes a dedicated Full-Speed (12 Mbps) USB 2.0 trans-
ceiver supporting all four USB transfer types: control, interrupt,
bulk, and isochronous. The maximum data payload size is 64
bytes for control, interrupt, and bulk endpoints and 1023 bytes
for isochronous. PSoC Creator provides full configuration
support. USB interfaces to hosts through two dedicated USBIO
pins, which are detailed in the
on page 27.
USB includes the following features:
