7.1 USB
PSoC includes a dedicated Full-Speed (12 Mbps) USB 2.0
transceiver 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
Routing”
USB includes the following features:

7.1 Timers, Counters, and PWMs
The Timer/Counter/PWM peripheral is a 16-bit dedicated
peripheral providing three of the most common embedded
peripheral features. As almost all embedded systems use some
combination of timers, counters, and PWMs. Four of them have
been included on this PSoC device family. Additional and more
advanced functionality timers, counters, and PWMs can also be
instantiated in Universal Digital Blocks (UDBs) as required.
PSoC Creator allows designers to choose the timer, counter, and
PWM features that they require. The tool set utilizes the most
optimal resources available.
